Ground source heat pump provides eco heating for new build home

A brand new farm property has taken advantage of spare land to install an eco-friendly Ground Source Heat Pump system.

A brand new farm property has taken advantage of spare land to install an eco-friendly Ground Source Heat Pump system.

The Stiebel Eltron WPC10 heat pump will provide energy efficient heating and hot water for the new build 4-bedroom home in Newton Grange in Ashbourne, Derbyshire.

Stiebel Eltron UK worked closely the building and plumbing contractors on the design and installation of the system, which utilises a 500m ground loop in land adjacent to the building.

The WPC10 has been combined with a 200 litre hot water cylinder and 200 litre buffer vessel to provide green energy at a vastly reduced cost compared to gas or boiler systems.

The 200sq m home, which includes one family bathroom and one en-suite, has been fitted out with underfloor heating on the ground floor and radiators on the first floor.

It has been purpose-built for the owner, whose family owns and runs a farm and hotel within the same countryside complex.

The owner said: “I had heard good things about green energy and always wanted to consider it when the property was being designed. The developer and plumbing company suggested using Stiebel Eltron UK, and Chris Johnson from the company came to meet me to describe the benefits of their products.

“Chris showed me the designs and all the figures for costs and savings and this was a big factor – for example I am saving around £250 per quarter in fuel bills alone.

“The customer service and support was excellent and once the system was installed and set up, I was shown exactly how to use it. Everything is now running smoothly and efficiently, and I don’t have to worry about issues like boiler maintenance. The heat pump and cylinder are discreetly out of sight and run very quietly; the team have done a great job with the installation.”

The WPC10 offers a complete solution for Domestic Hot Water (DHW) and central heating, drawing its heating energy from geothermal loops in the ground. The unit contains a 200-litre cylinder under its noise-insulated external casing and all safety and control components for a fully automatic operation are already integrated into the design.

A spokesperson for the building contractor said: “On past projects I have struggled with other manufacturers to get the right design and specification. Stiebel Eltron gave us a prompt response and came up with the perfect solution, with Chris Johnson from the company supporting us from start to finish – he also gave us the confidence that the product would work.”

Chris Johnson, Regional Specification Manager for Stiebel Eltron UK, said: “This project was perfect for a ground loop system due to the available land space next to the property. We find that a lot of farm and land owners will opt for ground source heat pumps as the best solution for their green heating needs.

“The WPC10 requires minimum effort to install, even in very tight spaces and provides high energy efficiency (with a COP of 4.5) and substantial cost savings against fossil fuels.

“Domestic properties with Ground Source Heat Pumps will qualify for the Renewable Heat Incentive from this summer (2013), while some households can claim the Renewable Heat Premium Payment and still be eligible for the RHI when it kicks in.”
