hi folks am truly at the hair pulling stage and need to finalise my heating design with the next few days. i had decided on a vertical bore ground source heat pump with underfloor heating. from following threads here and eleswhere i am seriously questioning my choice.
i have a ber spec compiled along with heat demand etc.
House details 150mm cavity bead filled.
all external walls are drylined with kingspan 38mm boards
i have also installed triple glazed windows, composite U-value of 1.1
house is air tight also and MTD HRV unit installed
so what to install, my good wife wants underfloor through out, however we could put radiators upstairs.
two options
1. condensing oil boiler + solar panels
or
2. geothermal heat pump, air to water or ground source
i am not interested in wood pellet etc, too much labour involved and i dont have the space
my big problem is the cost of geothermal, and if i will ever recover the initial outlay.. second problem is i dont go geothermal whats the best option to work with underfloor heating...
thanks in anticipation
