We're in the process of having one installed - with 600m of collector pipework in three trenches. Out here in Ireland the estimate for the work was in the region of 12000 euro - quite a lot of which is for the 'groundwork'. Good news is that out here there's a government grant for 4000 euro. The heat pump itself is rated at 2kw - and is reckoned to return 2-3 kw of heat for every kw of electricity. The system we're having has two pumps, one for whole-house heating and the other for when you only want domestic hot water... If you need any more info then please ask Regards Adrian |

We had a bit of ground that dipped rater inconveniently, and we wanted it levelled for a polytunnel, so we half-excavated / half-filled the area - so that the collector pipes are in trenches 3ft deep with 3ft of soil on top of the original ground level (if that makes sense). Because we had the space, we just installed three trenches at about 50m each - and put two loops of 100m-long pipe in each. These come back to a couple of manifolds (like you'd use for underfloor heating) - and then to the (still-to-be-installed) heat pump. If you're stuck for space, it's also possible to install the ground collector in a narrow vertical borehole.... I'll try & remember to let you know when we've got the system commissioned.....

Hi I have seen these pumps installed as you mentioned on a vertical
bore hole some 30mts i think .I do remember there where concerns over the noise levels allthough I dont know if these where founded . They also installed a gas supply as a precaution . Pablo |

I installed a ground source heat pump 4 years ago into a barn that i
was converting. The groundwork, in my case, was much greater than initially expected since 2 rock seams crossed the route of our pipework. I have since been involved in 2 other settings both of which went very smoothly. As to the payback... if you are not on mains gas then the sums work out. Just calculate the annual cost of a mortgage of lets say £8000 and I think you will find that annual outgoings are less than your savings. In addition you are also doing your bit for the environment. Would I do it again? Yes!!! Have I recommended it to friends? Yes!!! Are there drawbacks? Yes!!! The main one being that unlike conventional boilers the units are not oversized and so recovery time tends to be longer. I tend to run my for 8 hours at night (cheap electricity) and then just top ups throughout the day. With my system I also get all my DHW from the system... there are mixed views on this, but I am pleased with the results and the efficiency. If you want a chat about it then get in touch.

Hiya
Sorry I havent replied to your post earlier. I have been working away from the office. I have no problems with you either emailing me or phoning me to discuss the heat pump... though emailing is probably the best route as I am rarely in. The best email to get me on is Kind Regards Calum Sabey NewArk Traditional Kitchens 01556 690544 |

The install cost is way too high, so much so it is better to install a cheap oil or LPG boiler and use the remainder of the money spent on a heat pump on heavy insulation and making the place more air tight. That will give a house that is much cheaper to run than a heat pump and technology that is easily and cheaply serviced. |

You've just pointed out that the money spent on a ground source heat pump might be better spent on insulation and other energy conservation measures then you go and recommend solar heating to which the same considerations apply in spades! |

That will give a house that is much cheaper to run than a heat pump and technology that is easily and cheaply serviced. Surely a heat pump ought to run for years without problems: my old fridge was still working fine when I dumped after 24 years. For those not of a DIY persuasion, oil or LPG will cost £100+ per year in servicing and replacements and you have the issue of fuel storage and deliveries. The other big advantage of heat pumps on new builds is that they make complying with Part L much easier. The compliance test is now CO2 based. Electricity is assumed to produce about twice as much CO2/kW as LPG. Factor in the respective efficiencies 300%/90% and the CO2 for heat pump sourced heat is significantly less. Using solar panels for DHW would make sense since heat pumps are not at their best producing really hot water, rather warm water feeding into underfloor heating. -- Tony Bryer SDA UK 'Software to build on' http://www.sda.co.uk |
