Tailored hardware packages
Correct sizing of your heat pump involves a comprehensive assessment of your property including accurate calculations around energy usage and heat loss. We will do this prior to installation.
For the moment, based on high-level information, we have calculated a heat loss of 9.9kW and assumed 4 occupants.

Indicative savings
We can provide you with high-level indicative savings you can expect to make through replacing your boiler + radiators system with a heat pump. If you proceed with the installation, we will provide you with an MCS accredited design which will provide you with accurate payback information.

Your main heating system is a boiler + radiators system supplied by gas. This is also used to heat your hot water. Tell us more about your current gas bill.

Adjusting your energy usage
Time-of-use electricity tariffs are designed to encourage you to use electricity when it is cheaper. If you set your heat pump to turn off between 4pm and 7pm, you can save money on your energy bill on certain tariffs. You can use this toggle to see how this might affect your savings.

For the purposes of this indicative illustration, we have assumed that your existing boiler + radiators system has a seasonal efficiency of around 85%. We have assumed that your new heat pump system will achieve a SCOP of 3.78 at a flow temperature of 50°C. This is based on the highest achievable SCOP from the product specification (1).This may vary when we carry out a full detailed design and specification. Approximately, this makes your new heat pump system 4.4 times more efficient than your existing system.
For your current gas supply, you have indicated a per kWh cost of 6p and a standing charge of 31.4p. For the purposes of the illustration, and based on the tariff you have selected, we have assumed that the average cost of electricity is 22.79p per kWh. Based on national averages, we have assumed that 12% of your total energy consumption is used for hot water.
* Standing charge adjustment. Most homes already pay a daily standing charge on their existing electricity supply. For this comparison, we have not counted that full charge again — only the change between your current rate and the rate on your selected heat pump tariff.
Your current electricity standing charge is 51.81p per day (around £189 per year). Your selected heat pump tariff has a standing charge of 47.4p per day.
Your selected tariff is 4.41p per day lower than your current electricity standing charge, so the figure marked * above reduces the heat pump costs by £16 per year.
Additional options available for your system
As part of the survey, we can discuss extras that you might need or want beyond the standard heat pump installation. You can play with these extras below to see how they might affect the overall cost.
Intatec Heat Pump Fitting Upgrades
