Installation of a ground source heat pump, solar PV system and MVHR.
The project involved the replacement of an existing dwelling in a rural setting with a new four-bedroom house with a detached garage/workshop set on a large plot with adjoining paddocks. The client wanted to create as an environmentally friendly home as possible with the benefit of low running costs.
The plot was surrounded by paddocks, so a ground source heat pump was the ideal solution to provide clean sustainable low-cost heating and hot water for the property, which was to have under floor heating throughout.
High levels of insulation were built into the fabric of the building, so a Stiebel Eltron 13kW ground source heat pump was more than capable of meeting all the needs of the home. Renewable heat was to be gathered via five 150m collector loops buried in the adjoining paddock. The heat pump itself, along with a 400 litre hot water cylinder and 200 litre buffer tank were located in the plant room adjoining the detached garage/workshop. Pre-insulated pipe was buried between the plant room and the house to minimise any heat losses.
Two Brink MVHR units were installed at first-fix stage of the construction to allow the radial ducting to be fully concealed.
The compliment the other renewable energy technologies and to provide a free source of electricity, a 4.2kW in-roof Solar PV array with Solar Edge inverter and optimisers was installed over the garage/workshop.
