geothermal help

    To all the usual suspects,

    We would love to install geothermal but since we got our initial quote we have been finding hidden costs and we are now worried that it will bring us over budget. We are now deciding between keeping the timber windows or the geothermal. The added costs include having to re-enforce the timber frame structure of our house to cope with the screed floor for the underfloor heating and we have to increase the number of pipes for the underfloor so it works at 35 degrees along with rectifing some site problems. My question is would it be possible to prepare for geothermal and do the extra pipes in the underfloor and get a normal boiler to work the heating at 35 degrees and then in a year transfer over to a heat pump? If it is possible this may be the practical solution even though I really want to keep the heat pump.

    What do you all think?

    Eve

    You could do that setup alright. Personally I think in the long run you will need to buy a boiler, then sell it at a lot less of the paid price, then install the heatpump. It is route I would not go down.

    What you could do is not screed upstairs and just put down a 50mm batten, 25mm kingspan between the battens and lay your pipes between the battens also. Now that does force you down the route of putting timber flooring but it is one option.

    On the underfloor heating, Climate Control wanted me to go with them for the UFH as it gives 35 degrees etc.
    I went back to under floor direct and they can put in extra piping to decrease the temp down to roughly 39 degree C.
    Even with the xtra cost these are coming in at about 4500 euro with 5 TP5 thermostats.
    What I am finding in the house is that anyone that has come into the house since we insulated over the last week has commented on the serious heat.
    What I am hoping is that if I also insulate the ground floor roofspaces that this will give us even better heat retention and therefore keep the temp high, so leaving the heatpump with not much work to do.

    Hi Eve,

    I found Climate control expensive on the UFH, (this must be due to extra pipes for the 35 degree's) over all they were a few grand more expensive then my previous front runner. Maybe take a look back at some cheaper quotes and see if they would work better for your budget. Like Yop I don't think I'd like to go down the reg boiler and change a year later route. I think it would be alot more expensive in the long run and will you really change over in a year?
