Re: Renovation project - need advice

Ten years ago did similar renovation in my current house - similar size and dating back about 80yrs. old.

If the 18k (approx. 21.5k chufs) is for both heating and lecky, then that's probably there or there about what it's going to cost.

Trying to recall my costs - approx. 10k chufs for lecky (all new) and 40k chufs for heating - warme pompe with 90m bore-hole - everything completely replaced (from a wood burning stove for radiators and hot water). Hot water, now is also provided by a separate air-type warme pompe "boiler" (in cost of heating). In older properties special heat-efficient radiators are used instead of the more conventional under-floor heating (again in cost).

Today, an air warme pompe for heating would be cheaper to install (compared with erd sonde type) as no boring is required - although more expensive initially, after about 10yrs. you will start to save money, due to no fuel costs (except minimal lecky).

And it's no fun on a cold winters morning to get up in a cold house and start a wood-burner, before the house becomes warm.

With any heating system (especially warme pompe), in an old property insulation and draught exclusion need to be top notch - and may be an additional, unforeseen expense.
