Enhabit has recently designed, supplied and installed the mechanical ventilation with heat recovery (MVHR), Solar photovoltaic (PV), air source heat pump (ASHP) and underfloor heating systems for a low energy newbuild project in Surrey.
Design
The project was aiming to be as energy efficient as possible, with an efficient building fabric provided by a Kingspan TEK plus timber frame construction. Consultants MESH Energy suggested the renewable systems for the project and then produced a tender document with an outline of the systems and a possible system make with the final decision by the final provider Following the tender process. Enhabit was chosen to deliver the services and make final decisions on the systems required.
MVHR
An MVHR system was required to help retain heat within the building, as part of the project’s energy efficiency measures. The Zehnder ComfoAir Q450 MVHR system with 100% Variable Summer Bypass was specified by Enhabit for the project. Enhabit designed, supplied, installed and commissioned the MVHR system, along with a ComfoSense control panel and rigid steel spiral wound ducting.
The clients commented:
“The Zehnder ComfoAir Q450 is working really well for us. It is easy to run and control – with a control panel in our kitchen or on our Ipad. The air quality in the house has been excellent and we’re noticing less pollen-related allergic reactions. The system is also very quiet in operation – we don’t hear anything”.
Air Source Heat Pump & Underfloor Heating
Enhabit designed supplied and installed the Mitsubishi Ecodan Monobloc Air Source Heat Pump (ASHP) along with a 300L cylinder for hot water. The ASHP is used in conjunction with 200m2 of underfloor heating, which Enhabit also designed and installed. The ASHP provides underfloor heating and hot water.
The clients commented: “The ASHP has been very easy to run with the hot water set to 50 degrees. It is also quiet in operation and doesn’t annoy our neighbours. We are pleased to get some return on the investment through the Renewable Heat Incentive”.
Solar Photovoltaics
The project also benefits from 12 solar PV panels on the roof, which Enhabit also designed, supplied and installed. The specification was for 12 X 325W LG panels, with a 3.5kW Solaredge converter.
Overall impressions
The clients commented: “Enhabit managed all the heating and energy services for our project. It was really helpful to have one place to go and to have one company overseeing all the various elements. Enhabit were very responsive and the whole process went very well”.
