Water is a good store for solar energy as even on cold days groundwater maintains a constant temperature between 7 and 12 deg The groundwater is extracted via a supply well and transported to the evaporator of the water/water heat pump and returned via a return well. Outside air offers the least expensive option for exploiting an energy source. Air is supplied via a duct put through the heat pump and returned to the outside ambience.

All units transfer solar energy from the ground into a building, where a compressor converts that energy into warm air or warm water. Options on various models include two-speed compressors, demand water heaters, quad functions and electronic diagnostics, among others. Units should be certified to ISO performance levels (formerly CSA or ARI rating), to make the COP the key variable among different manufacturers.

No. There are different kinds of geothermal heat pumps designed for specific applications. The most advanced systems use vertical bore holes and direct expansion technology. Some geothermal heat pumps provide summer air conditioning, radiant infloor heating and heat for domestic hot water use, but a few brands are designed only for winter heating. Sometimes these heating-only systems incorporate a groundwater-cooled coil that can provide cooling in moderate climates.

We expect that our "Performance Plus" heat pumps should typically last 20-25 + years. Naturally this all comes down to the conditions the heat pump is in, and regular maintenance.

Heat pumps are generally very quiet, noise levels equivalent to that of a fridge. We would always recommend you listen to one before you purchase.

Yes. Through our electric supplier TVA we offer a program that allows our residential customers who own their homes to install a heat pump and have the payments placed on their utility bills each month. Terms of the loan are 8% interest for a period of up to 10 years. You must use a TVA-approved heat pump contractor. Rebates are also available.

Underfloor heating works well with heat pumps as they give a constant low heat temperature. This sort of heat pump works very well with larger projects, unlike extensions, where they become costly.

No. HomeTech's Heat pumps are designed to be unobtrusive in their size, are neutrally coloured to fit into your décor. They run at a low noise levels so as not to be noticed.

No. Heat Pumps are generally not noisy. The source of noise in a heat pump is usually the air being blown through the grill as it is forced out of the unit. Air noise is marginally higher than ambient background noise and is usually not distracting.

Heat pumps transfer heat by circulating a substance called a refrigerant through a cycle of alternating evaporation and condensation. A compressor pumps the refrigerant between two heat exchanger coils. In one coil, the refrigerant is evaporated at low pressure and absorbs heat from its surroundings. The refrigerant is then compressed en route to the other coil, where it condenses at high pressure. At this point, it releases the heat it absorbed earlier in the cycle.

All Daikin, Mitsubishi and Panasonic heat pumps use the R410A refrigerant. This is significantly more environmentally friendly than the older refrigerants.

Heat pumps are very reliable ? particularly the brands we recommend: Daikin, Mitsubishi and Panasonic. They use the same process as a domestic refrigerator and have the same level of dependability and life expectancy.

The only on-going maintenance a home heat pump needs is the cleaning of the indoor air filter, which should be done approximately every 8 weeks. This is an easy task and instructions can be found in the manufacturer's manual which comes with your new heat pump.

Virtually all heat pumps are available with supplemental electrical heat. Some heat pumps are used in conjunction with a, fossil fuel heating system such as gas or oil. Whether supplemental heating is necessary depends on your climate and home location. Your local contractors can advise you as to whether supplemental heat is necessary, and what type of heat pump might be best for your needs. A heat pump can be a worthwhile consideration no matter what heating system is used in a home.

With over 30 years of heat pump pool heater design experience, Rome Heat Pumps are built to outperform the competition. Advanced micro-computer technology and exclusive design features result in 25% more heating performance than other leading heat pumps. Unlike most other heat pump pool heaters, which use off-the-shelf components, Rome Industries uses components specifically designed for optimum performance. This means higher efficiency and lower operating costs than competitive heat pumps.

air health will work on all types of warm air furnaces and split unit heat pumps. air health is designed for indoor mounting only.

The UV Sterilizer will work on all types of warm air furnaces and split unit heat pumps. The UV Sterilizer is designed for indoor mounting only. Yes. The UV Sterilizer uses powerful UV light to help reduce and kill mold, bacteria, viruses, dustmites and other airborne invaders.

Centrifugal pumps are made in many shapes and sizes, and differ from one another both internally and externally to an appreciable degree. In spite of appearance, all centrifugal pumps use the same mechanical principle. Pumping action is obtained from an impeller driven by a shaft or magnetic coupling which is connected to a motor or some other driving device.

The most popular types are gear (also known as rotary) pumps, vane pumps, and piston pumps. Pumps are rated by horse power (hp), shaft type, shaft size, direction of shaft rotation, gallons per minute (gpm) flow and pounds per square inch (psi) pressure.

a normal function of all heat pumps, the unit will automatically and periodically defrost the outdoor coil. The unit's sound will change and the unit will also circulate cooler air during this cycle. On average, the defrost cycle should last approximately three to five minutes. Do not turn the unit off during defrost, as this only prolongs the cycle. (If the unit's thermostat has been set back or turned off, the unit may not defrost within a normal time period.)

No. The equipment goes inside your home, usually in the basement, garage or crawl space. Because it's indoors, the life span of the compressor and major components are greatly extended, most having a life span of 20 years or more.

Standard radiators operate with water temperatures of 60°C to 70°C. Under floor heating can operate at temperatures as low as 40°C. Heat pumps are far more efficient when operating at these lower temperatures. Because ground source heat pumps draw their energy from the ground they usually require a large collector area, this may not always be available, in this case an air source heat pump might be more suitable.

Apart from being cheaper to run than any other form of heating, Heat Pumps offer many more benefits than any other heating systems. Heat Pumps do not burn oxygen or create stuffiness like open fires. They are designed for year round comfort not just the 4 months of winter. Heat Pumps produce low density heat which is safe for children and the elderly, unlike fires or electric heaters. They are unmatched for convenience for ease of use (Remote Controlled).
