Ground source heat pump – Thirsk
Your name or initials and geographical location if preferred? Ken Johnston – Thirsk North Yorkshire
Was this a new build or an existing building? Existing Building, originally built in 1950 bungalow with an brick/block unfilled cavity and solid concrete floors, a mixture of single and double glazing units with an insulated loft 100mm). we converted to open plan and loft conversion
Did you decide on an air or ground source heat pump? Following many hours/weeks/months of research and due diligence on the internet we decided on a ground source heat pump. I spoke with many manufactures (NIBE, KENSA, OMNIE, WARMFLOW Etc) as I wanted an integrated hot water system at mains pressure
What type of heating did you have previously? Being rural with no mains gas supply, we were on heating oil.
Why did you decide to work with Yres? There were a number of companies I asked for a quotation, many chased me for sales and with doing a full renovation, back to brick and living in a caravan for the 8 months the last thing I needed was badgered by sales people. I initial sent a request for quotation into YRES and Gary phoned me to talk through the possibilities and realities of what I wanted to achieve, they were the only company that gave me a quick general price for the GSHP unit (Nibe 1255). As with any new technology, there are uncertainties and Gary was very honest in discussing these upfront. He never badgered me to chase the Sales and was informative and thus that is why I decided to work with YRES.
How would you describe working with the people at yres? Its does frighten some contactors when you have done so much research that potentially you know the product (academically) better than them. What I got from YRES was (Gary/Mark) that they could have an adult conversation about the installation, setup, running etc. So fundamentally professional but able to communicate at the right level.
Are you satisfied with the installation? Overall yes, initially as discussed with Gary/Mark on the installation day, I was not expecting an additional 100lts buffer vessel with the installation (space is a premium), the requirement was explained too me. The installation was done to a high standard as I was expecting.
Does the heat pump deliver what you expected? My wife feels the cold, she does not like oil heating, didn’t want a potential noisy ASHP, didn’t want a biomass burner and most of all wanted to be warm. The GSHP from NIBE installed and serviced by YRES combined with UFH delivers on her requirements. The house is well insulated and as airtight I could make it. This means we have a constant warmth in the house without it being too hot and stuffy even when its snowing outside we can walk round in shorts and t-shirt. I have a plant room (boys cupboard to look at pipes, valves, gauges etc) and my wife has an environmentally friendly, quite and economical system – we have spent £300 on heating and hot-water (Nov 2018 to Nov 2019) that is £250 pounds less than when we used heating oil.
Would you recommend yres to others? Yes, I do with everyone I have conversations with about ASHP/GSHP
Any other comments you would like to share? The capital cost is large (but worth it), whilst available the RHI contributes to that return in investment over the 7 years (GSHP), plus you are not directly using fossil fuels.
Get a heat loss calculation done so you know what your heating requirement will be.
Insulate your home bottom (floors), walls and roof – the better insulated the less you will spend on electric to heat the house.
Ask questions, if you don’t know the questions to ask, ask to speak to someone who has had one installed (all houses/locations are slightly different).
If I was to do it again, I would get YRES to do the full installation from Borehole, GSHP, UFH. There are costs, but quality counts and the system will work at its best.
If your having carpet put down on a UFH floor – do not let them use standard underlay, no matter what they tell you! (get the right UFH underlay yourself if you have too)
9:00am – 6:00pm
I switched from LPG to a Ground Source Heat Pump. The savings have been huge, it is also far easier to manage – I don’t have to worry about heating. By far the best investment I’ve made in my home.
Excellent prior, during installation and after care
They listened to our requirements and made several good suggestions as the technology has moved on considerably since our original system was fitted
They are very professional, friendly and will go the extra mile to explain all the technical aspects of this type of heating system and the scheme
