If my mates in the Electrician's Forum see me in here, jus' tell I got lost, alright ;)
So, I was called out to the home of a good client. They have a thermal solar installation but were not completely clear of the difference - hence calling in a sparky and I was interested as to how thermal...

My site is on the side of a hill and the...

Hi
Can somebody tell me if a standard heat source pump installation uses a pressurized hot water tank? Or will the pressure for the hot water be the same as with my oil boiler and water storage tank (gravity-fed)?
