The Homemade Heat Pump Manifesto

Unless the current radiators are fan-forced there is not enough heat available to make your living space comfortable. The heat pump produces a water temp. around 40 Deg. C. And this may not be enough for a convection type of radiator. However a fan forced radiator may be enough but it would run longer on a low speed setting which may do the job and keep you comfortable.

I had installed a fan center (fan behind radiator)with DIY GSHP in my shop and its working extremely well saving a ton of money. I used to burn dinosaurs as well. Diesel $2800 for heat. Heat-pump less than $1000.00 for a year

Ground source heat pumps coupled with in-floor heating is the holy grail IMHO and is very economical. However the house must be well insulated and sealed against fresh air blowing through it. $2000.00 for a complete system even DIYed might be a little optimistic if you include the ground loop.

I'm not sure of your climate in Portugal but the Mini-split heat-pumps look very interesting.

As you are starting to understand we are entering an interesting time. Solar panels coupled to heat-pump keeping the family home warm.!!! Although its a little simplified in that statement but its now being done.
