David and Gill ticked something big off the bucket list in 2018 when they built their own home. They purchased the perfect plot and knocked down the 1970s Bungalow that once stood there to make space for the home they had always dreamed of: an architecturally designed, eco-friendly property with low running costs and a low carbon footprint. They set a target to achieve a minimum Energy Performance Certificate (EPC) rating of A92.


The couple’s desire to build an exceptionally efficient home drove their decision to install a NIBE air source heat pump (ASHP) for year-round heating and hot water generation, complemented by an MHVR system and underfloor heating in all areas of the home. Local NIBE VIP Installers, Energy My Way installed the NIBE F2040-12 ASHP alongside a 200-litre Megacoil hot water cylinder and a UKV 40 Buffer Vessel and a NIBE SMO control module combined with the NIBE Uplink service. Going one step further, Energy My Way also incorporated a bespoke solar PV system onto the new raised seam flat roof to allow for onsite energy generation to power the heat pump and provide free hot water use in the warm summer months.


Of the twelve months it took for David and Gill’s dream home to be constructed, it took Energy My Way just six short weeks to complete the installations described above. Amendments were made to the construction throughout the process to ensure that the project was in line with the couple’s target EPC rating. With the assistance of the NIBE heat pump and solar PV system, the final EPC rating exceeded expectations at A97 rather than A92. This secured David and Gill a preferential rate ‘Green Mortgage’ and supported the couple’s goal to live in a low cost, low carbon home. The annual heat demand for the property was initially projected at 19,544 kWh but the team surpassed this, delivering a home with an estimated demand of 7,845 kWh for heating and 2,308 kWh for hot water, as indicated by the as-built EPC – the calculation taken once the building work was complete. The heat pump itself has a Seasonal Performance Factor (SPF) of 3.67, meaning the couple now benefit from renewable heat incentive (RHI) payments equating to £725 per year.


Dan and Gill’s low carbon home featured in The Housebuilding and Renovation Magazine: “We just absolutely love it, it’s amazing living here. Every morning we wake up and cannot believe we’re living in this dream house.” NIBE is delighted to see the couple enjoying the benefits of the air source heat pump, installed into the home by Energy My Way in January 2019.
