Hi there, thanks for your time to look at this. I've done an estimated heat loss calculation on Heat Engineer - which comes out to 20kw approx for a 5 bed house. They also calculate total energy demand of 55,000 kw? Assuming you have a gas boiler, is this what the gas consumption should be...

Hi there, I have two old Geminox 200 litre tanks (EBS 200) below plumbed in paralell - I think from 2007 originally. I believe these are the specs below. I'm trying to work out how much energy they should consume to heat the tank from lets say 40 degrees to 55 degrees after two kids have...

Hi there, thanks for taking the time to read this. I've been trying to diagnose why my gas consumption is so high and been doing various measurements and tests. With the UFH, my setup is about 10 room zones connected on two separate UF manifolds linked to one UF pump with a return blending...

Hi there, I've already posted on the forum but I need an experienced heating engineer to determine what changes to make to my system - please let me know if you can suggest anyone covering north west London (not far from Watford) who can deal with system design and complicated wiring. Thanks...
