An Air Source Heat Pump (ASHP) is an energy saving unit which transfers heat from outside to inside a building, by storing it in a unit that can be used when needed. Website Terms of Use * Contact UsCopyright © 2020 Great Home, Replacement Boiler Cost Online Calculator. The ideal energy saving unit works by using vapor compression refrigeration, which involves a compressor and a condenser to absorb heat from outside air and releases it through your existing radiators, under floor heating, or warm air convectors and even the hot water in your home.

Like a gas boiler it provides heat to supply hot water and space heating. This means that a flow of water is available, even when the ASHP is not operating. Air source heat pumps are generally cheaper and easier to install in the home than ground or water source heat pumps although their “Seasonal” COP will be lower. Hence, from a carbon perspective, it makes sense to replace a gas boiler even if it was just installed. display: none !important; Pipework also needs to be bigger, as flow rates are higher to compensate for the lower water temperature. It can be used instead of a boiler, and is self sustaining saving you hundreds of pounds per year.

One option is to use the Renewables Guide Quote Service. It can get heat from the air even when the temperature is as low as -15° C. Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally. The ASHP maintenance would include: Feedback from those with heat pump already operating indicates that the quality of the design and installation of the system are key to getting an effective system. It offers an independent view, trying to balance the interests of … read more, * Cookie & Privacy Policy * Alternatively you can find individual Microgeneration Certification Scheme (MCS) certified installers by visiting the MCS website. this would deliver a cost benefit at a lower COP.

This is because in winter using the ground or flowing water as a heat source gives access to warmer and more consistent temperature than the air. If you own an old draughty home which costs a lot to heat then installing decent levels of insulation and cutting down on draughts would be essential.

Shame I didn’t know about the boiler scheme until after winter, but overjoyed to have my ancient boiler swapped for a brand new one – and for free! timeout Time limit is exhausted. In many cases, yes, a heat pump can provide all the heating and hot water you need for your home. thirty five

If you own an old draughty home which costs a lot to heat then installing decent levels of insulation and cutting down on draughts would be essential. It may be smarter to spend the money on upgrading the insulation in your home, reducing the energy required to heat each room; in this case the old radiators and pipework may then be suitably sized to heat the better insulated room with a heat pump. All matter has something called ambient energy, which exists even below "freezing" temperatures or below 0°C. Air source heat pumps are installed outside the home, so there are some considerations related to where the pump can be mounted (no closer to the property boundary than one metre) and to avoid visual intrusion (particularly in listed buildings). The scheme provides Government funding for energy-efficient, Air Source Heat Pumps, which reduces carbon emissions and can save around £500 per year on your fuel bills. To reduce system cycling and improve efficiencies some manufacturers and installers will sometimes recommend use of a 60-100 litre buffer tank to increase the heated water in the heating system. The ASHP can continue to run for a few extra minutes, even when there is no call for heat from space heating or water heating, which reduces system cycling. Local install team were very knowledgeable, Got my walls insulated for free, told my neighbour and she was able to get hers done too, house feels much warmer now, Loving my new Air Source Heat Pump, much quieter than I thought it would be and very efficient so far, After some minor damage to my property during install Saving Energy Group had the problem rectified very quickly, refreshing to deal with a company who take pride in what they do, Got my loft conversion fully insulated through Saving Energy Group, the install team even plastered and decorated the walls afterward, best phone call I made all year.

Hi I'm Jon.

if ( notice ) Upgrading of any electrical wiring, the hot water cylinder and the control system will probably need to be done with either a replacement gas boiler or a heat pump.

Replace your Oil Boiler with an Air Source Heat Pump. We have both a part-funded option for a cost of £5,000 or a full price option costing £13,000 which pays for itself entirely after only 7 years. ); A site survey would need to be done by a Gas Safe Registered Installer, to identify if any or all of this work needed doing. Great service, install team polite and efficient, Great company, very professional and friendly, Office: Southwest Energy Centre, Long Road, Paignton, Devon, TQ4 7BL | Copyright © 2020, Saving Energy Group, Which Option will be right for you? That said, people are most suited to well insulated quality built homes as well! Very impressed! The other components of the two systems are similar in costs and installation time (pipework, controllers and control valves). })(240000); To qualify for RHI payments and to maintain warranty on the product the system should be serviced annually by a MCS certified installer. In comparison, space heating can be operated with lower temperature gains, typically 35°C. The ASHP itself looks much like a stand-alone air conditioning unit (see simplified image) and sits on the outside of your home. The RHI that the government will pay depends on your current carbon footprint and we have calculated that if you currently have a high carbon footprint, the fee paid by the government over the next seven years can be greater than the cost of equivalent loan to buy and install an air source heat pump, effectively making it free for qualifying households. }. Houses that have installed an air source heat pump will have lower fuel bills and lower carbon emissions depending on which fuel has been replaced. is needed at higher temperatures than the heat pump can achieve, an electrical heater element may be needed to top up the last few degrees. Pipework with an increased diameter will also be needed. Deciding whether to replace an old gas boiler with an air source heat pump depends on a number of factors. It is smart to make your home as energy efficient at possible before you decide on the type and size of a space heating system. During frosty weather the system will occasionally have to go into a defrost routine to avoid ice build up on the heat exchanger. This website seeks to help those searching for the basics about improving their home. These differences make it generally more cost effective to install a heat pump in a new home, rather than having to change over an existing gas central heating system, However, if a house with an existing gas boiler has been upgraded with better insulation then the overall heat demand will be lower and will make an air source heat pump more attractive. Alternatively you can opt for a part-funded AIR SOURCE HEAT PUMP system for a cost of £5,000 fully installed, where you benefit from endless hot water and heating, and your funder retains the R.H.I.
