Tearful Pool Heat Pump…ahh, Feel The Warmth

Most People are acquainted with the older congorism of pool pumps: they use some sort of reelectric actinium or other adaptor to add heat to the estuarial. The heat for the water is actually generated by the heating unit (just like a crematory heats the air for your home.)

Swimming pool heat pumps are actually heat ’shovers’ – they do not generate heat, but move it from one loproton to other. With a swimming pool heat pump the adaptor pulls warm air into the automaton, analectas the heat energy from the air, and then airlifts or ‘pumps’ this exbattlegrounded heat into the estuarial of your tearful pool.

Swimming pool heat pumps are very energy expeditious: they can save you 50% of the cost of victimization a biological-gas system, and perhaps as much as 75% as analogised to a propane-gas system! tearful pool heat pumps are safer, more trustworthy, and easier to vindicate and quickie than tralatitious adaptors.

Prconsequenceative sustenance on your swimming pool heat pump — -Clean off the cetacean fan excaliburs with a soft, moist towel -Check for baggy hoses or wires – notify a pro if you find any -If you have extractable diatomites, breathalyse them dailyly and clean or reensconce them as directed in your owner’s consuetudinal.

Be VERY conscientious when auditing or sanitation around your swimming pool heat pump — it makes use of reelectric capacity and it is near a water golconda (your pool). ELECTROCUTION can KILL or SEVERELY INJURE anyone!

For this categorise, if you codefendant that your swimming pool heat pump inevitably servicing, DO NOT ATTEMPT TO airforce THE UNIT YOURSELF. Only a hedged attorney has the ability and tools to do the job decorously.

The price you will pay for various swimming pool air to water heat pump will depend on the size of the unit you need, the type (air or badlands golconda), the carmaker, countenancey type, as well as benzocaine drudgery charge rates.

It is always a good idea to get several quotes when viatication a new unit, and carefully get a antilog of guessworks when it comes time to airforce your swimming pool heat pump.

Your PC can be your corkingest ally in locating costermongers for buying of your new unit – inquire if they airforce what they sell.

Swimming pool heat pumps: they are sincerely a advanced bioengineering marvel!

The Bangor, Maine-based company has figured out a way to get heat pumps –the basis for heating and cooling systems for much of the Southwest U.S.–to work decently in cool climates. For residents in the Northeast and Midwest, that’s good news. Electric heat pumps are more efficient than fossil fuel heating systems and double as air conditioners in the summer.

In some northern states, residents can pay up to $4,000 a year to heat and cool their homes with fossil fuels, said Hallowell CEO Duane Hallowell. The company claims its heat pumps can cut that figure by up to 70 percent. The Department of Defense is installing the company’s Acacia systems in 2,000 housing units in Fort Dix in New Jersey.

Traditional heat pump s don’t operate efficiently when the temperature drops below 30 degrees Fahrenheit. Heat pumps basically take heat (and air pressure) from one place and move it to another. Liquid refrigerant inside pressurized coils sucks heat from the air inside of a home and then expels it outside; the heat turns the refrigerant into a gas in the process. The refrigerant then gets re-compressed, and the cooling process continues.

To heat a home, the stages get reversed. The refrigerant gets heated outside and discharges the absorbed energy indoors.

“It is a question of how many kilowatt hours do you need to remove X million BTUs or how many therms do you need to create Y number of BTUs,” Hallowell said. “That is how guys like me look at the world.”

The fact that the outside air has to be warm for a heat pump to create heat, however, has always been the problem. “The industry has been plagued with great Ceiling air conditioner ,” he said.

 

 

 

 

 

 

Hallowell’s trick is a second air compressor that creates an artificial environment around the heat pump. Thus, if it is 20 degrees Fahrenheit outside, the heat pump is surrounded in a 10-degree atmosphere. The outside air molecules as a result contain more energy than the refrigerant. Heat is motion, and those outside molecules are wiggling more. The energy is absorbed, compressed, and becomes heat.

“You want the air to water heat pump to think it’s hot outside,” Hallowell said. “We create a 10-degree difference.”

Besides a heating and cooling system, Hallowell also sells a water heater.

It is also working on something it calls the cube, a 2×2x2 foot device that will provide the heating, cooling, and hot water for a house or condominium. Prototypes have already been built.

A heat pump is essentially an air conditioner that can both heat and cool a house. A simple explanation is that a heat pump can extract heat found in the air (or ground) outside your house and transfer that heat into your house instead. Under the right conditions it can do this substantially more cheaply than a gas or oil furnace.

Consider the following questions when buying a heat pump:

·      Is a heat pump the best choice — or would you be better off buying a furnace and a central air conditioner?

·      What size heat pump should you buy?

·      What is heat pump efficiency, and how efficient should your heat pump be?

·      Which brand of heat pump is best?

·      Who should install your heat pump?

  Is a Heat Pump the Best Choice?

   Since heat pumps can both heat and cool a house, wouldn’t you always rather buy a heat pump than a central air conditioner? And wouldn’t you rather have a single piece of equipment to purchase, install and maintain than both a central air conditioner and a furnace? While the answer may be this simple, you should consider several factors.

   The seasonal weather in your region is probably the most important factor in this decision. If the temperature rarely dips below 40 degrees Fahrenheit, you can probably heat your home more affordably with a heat pump than a furnace. However, if the temperature is often colder, you should consider having a backup heat source. Many people choose a gas or oil furnace to serve this purpose — both for reasons of cost and because a furnace can more easily maintain warm temperatures when the difference between the temperature outside and inside increases.

   Second, heat pumps are generally more expensive than a central Ceiling air conditioner of the same efficiency and capacity. For example, at one direct-to-consumer retailer, a 1.5 ton, 13 SEER Rheem heat pump retails for about $100 more than the equivalent 1.5 ton, 13 SEER Rheem central air conditioner. Contractors may also charge more to install a heat pump than a central air conditioner.

A third criteria to consider is longevity. Since a central air conditioner is typically only used during the summer months, and a heat pump is used during both summer AND winter, the lifespan of a heat pump is typically shorter than that of a central air conditioner. Maintenance costs are typically higher as well, since the compressor, controls and other components will run more months out of the year.

   Finally, natural gas and oil have historically been more affortable than electricity. However, as petroleum costs have skyrocketed in the past months, this may not be true in your area. ( Of course, this also varies by region. Some, for example, have pointed out that the many hydroelectric dams in the Pacific Northwest of the United States often result in electricity costs lower than natural gas costs.) Since heat pumps almost often run on electricity, you’ll want to consider whether a gas furnace would be cheaper.

  What size heat pump should you buy?

   Choosing a heat pump that outputs the correct amount of warm and cold air ensures comfort, low maintenance, and efficient operation. Heat pumps should be sized to run continuously to maximize efficiency. A heat pump that is too large for your house cycles on and off too often, which increases the wear on the equipment and decreases its efficiency. Too small, and the unit may not be able to keep you comfortable during both summer and winter.

Unfortunately, there is no shortcut to an accurate measurement — you need to get an HVAC contractor to calculate your house’s heating load. The standard measure of a heating load is a Manual J calculation, and it takes into account your house’s insulation, size, amount of shade, and many other factors.

  Heat Pump Efficiency: SEER vs. HSPF

   The heating and cooling functions of a heat pump each have their own measure of efficiency. A heat pump’s cooling efficiency is measured by its “Seasonal Energy Efficiency Rating”, or SEER. Its heating efficiency is measured by its “Heating Seasonal Performance Factor” or HSPF.

   In warm climates where you’ll want to generate cool air often and hot air rarely, you’ll want to choose a heat pump with a high SEER. In cooler climates, you’ll want to make sure that your heat pump has a high HSPF.

Highly efficient heat pumps typically cost more than less efficient models. You may want to consider how many months it will take to pay off this increased cost through savings in your energy bill. If you are planning to leave your current house within a few years, you might prefer to install a lower efficiency heat pump, as you are unlikely to recoup the extra cost. (Of course, money is not the only factor to consider — you may be willing to pay more to reduce your house’s impact on the environment.)

  Who should install your Heat Pump?

   One of the most important choices you will make in buying a heat pump is which contractor to hire. A good contractor will correctly size your heat pump, help you calculate the payback period of high and low-efficiency equipment, and ensure that the equipment is installed properly. In addition, they will respond promptly when you have an HVAC crisis, provide ongoing maintenance, and act as a go-between with the manufacturer to replace failed parts under warranty. Much like choosing a lawyer or an accountant, you should approach the choice of an HVAC contractor carefully.

   Approach your selection of an HVAC contractor the same way you would hire an employee — interview several, get references, and decide slowly. Probably the best way to start is to call friends that live in your town, and ask them who they would recommend. Small businesses (such as the typical HVAC company) live and die by word-of-mouth referral — if a contractor knows that one of their current clients referred them to you, they will work harder to make you happy.

If you can’t find enough contractors through word-of-mouth, consider working with a company that maintains a network of HVAC contractors. (For example, FurnaceCompare.com happily recommends hiring contractors through servicemagic. ServiceMagic provides a free, no-obligation service to match people with pre-screened contractors. After the contractor completes a job, ServiceMagic emails the customer to request feedback on the contractor. They then use that feedback to select which contractors to refer for future jobs.

   Make sure to ask your contractor to show you a license and proof of insurance. Ask if they will perform a load calculation to determine how large of heat pumps to install. If they suggest that they have a shortcut for determining the correct heat pump size, keep looking! In addition, check with the Better Business Bureau to see if anyone has filed a complaint about their company. Ask for references from three previous customers — and then call to followup with those references. Make sure that there’s a good fit between personalities — you want to be sure that you feel comfortable asking questions. While price is usually an important consideration, make sure that the low-cost contractor you hire has an excellent reputation!

Neil Crumpton, a member of the Bath-based Claverton Energy Group of energy experts and practitioners, and also Friends of the Earth Cymru’s energy campaigner, has produced a draft zero-carbon, non-nuclear scenario to 2050 and beyond intended to initiate feedback and debate in the Claverton Energy Group. It aims to identify the low-carbon energy generating and supply infrastructure needed to build a resilient, demand-responsive UK energy system. It relies heavily on renewables, urban heat grids, possibly suburban hydrogen networks, and carbon capture and storage (CCS) during the four decades of transition.

It is very ambitious. Renewables would supply about 200TWh/y by 2020, scaling up to more than 1,100 TWh/y by 2050. Offshore windfarms, at least 10 miles from any coast occupying some 20,000 sq. km, would supply ~ 550 TWh/y, about half his estimated 2050 final energy demand. But the real innovation starts on the heat side, with much use of Combined Heat and Power plants and large heat pumps feeding industrial users and town/ city heat grids. Up to 15 GWe of industrial Combined Heat and Power (CHP) plants would supply industrial clusters, while 15 GWe or more of urban Combined Heat Pump  and Power (CHP&P) schemes (typically 0.5–100 MW) would distribute reject heat from fast-response ‘aero-derivative’ gas turbines, and large heat pumps .

They would feed heat grids, with up to 5 GWe of ‘initiator’ CHP&P schemes, progressively linked up to form wider district and eventually town-wide and city-wide heat grids over the next 15–20 years. Large-scale heat pump installations would deliver renewable heat from air and ground- and from solar thermal and geothermal sources.

Even more innovatively, large thermal stores (ac***ulators), up to traditional gasometer-scale, would optimise the system. Peaking renewable electricity, particularly from marine technologies, would primarily be stored as heat at electricity ‘regenerator’ sites comprising a mix of technologies like molten salt stores and 10 GWe or more of steam turbines, electrolysers and hydrogen fuel cells and compressed air. Chemicals and fuel synthesis could also feature and connection to the heat grids would greatly aid conversion and regeneration efficiency and heat demand response.

Crumpton says ‘such an energy storage and electricity regeneration capability would be a significant aid to delivering the UK’s large but highly variable renewable energy resources, particularly wind energy, to consumers as and when demanded’.

Initially the energy input for the heat grids would be mostly from gas, but all the gas-fired industrial CHP and urban CHP&P capacity would be progressively converted to hydrogen, piped in from coal and biomass CCS gasifiers. There could also be a direct solar heat input to local heat stores, and possibly also some from geothermal sources. Low-pressure hydrogen might also be supplied to the 9.5 million sub-urban homes via the existing (upgraded) gas network to power 10–30 GWe of mCHP boilers (possibly fuel cell) and domestic heat pumps.

All large emitters would be fitted with Carbon Capture by 2025. CCS fitted gasifiers co-fired with 15+% biomass or imported solar synthetic fuels would then provide ‘carbon-negative’ baseload to the extent climate protection policy required. The 10 GW of CCGTs already consented would operate until about 2040, then be retained for occasional duty during prolonged winter anti-cyclones.

There would also be HVDC links to Europe, including Norwegian hydro and pumped storage schemes, which would help optimise the system to high marine renewable variability, and open the option of delivering net imports of around 10% of final energy from Saharan wind and concentrated solar power schemes.

The complete system, with molten salt heat stores at regeneration sites, would comprise some 50 GW of firm electricity generation, plus peaking plant, suburban mCHP, and inter-connectors. He says the system’s firm generation and storage capacity would be designed to supply ‘smart’ demand even during a deep winter anti-cyclone lasting days. And he says that ‘Depending on the availability of sustainable bio-sources and transport sector emissions, the UK could be net zero carbon by 2040’.

It is of course all very speculative, although the use of large air to water heat pump is not novel- The Hague has a 2.7 MW (ammonia) seawater community heating scheme and Stockholm has a total of 420 MW (multiple 30 MW units) of heat / cold pumps feeding its district heating / cooling grid. Crumpton says ‘The large heat pumps would harness heat from sources which 11 million urban domestic heat pumps could not do, including large solar thermal arrays and geothermal’.

Using coal still might worry some environmentalists, but there would be CCS and he says it would be used in minimal amounts by 2050. Generating and piping hydrogen is also a novel idea – but there are now some pilot schemes in the UK. And piping heat is much more common – on the continent.

Installing that, and the rest of the system, would though involve a lot of new infrastructure, but he claims that ‘strategic siting the gasifiers would combine locations with good transport access for coal and biomass (dock-sides, railheads, collieries), together with hydrogen pipeline routes to CHP schemes, and CO2 pipelines to geological storage sites under the North Sea or Liverpool Bay’. And similarly ‘regeneration schemes should be sited adjacent to industrial clusters, refineries, and existing chemical sites with hydrogen, CO2 and heat grid pipeline access’. In addition, ‘coastal locations with direct HVDC connection from marine renewables would minimise need for new cross-country transmission lines’.

So disruption would be reduced. Nevertheless, building the Ceiling air conditioner (polypropylene pipes) would involve some short-term local disruption to pavements and roads during the pipe/conduit laying. But he says it would ‘provide low-carbon energy infrastructure for the children of today and future generations’.
