Don`t bother getting one they are shite, investigated the cause of my low
flow rates for ages and found nothing until I had a detailed read of the
manual. 7.6lpm maximum hot water flow rate.
I feel well stupid now, but then again, I did get it before I started
reading uk DIY. Its the only househould device I have which defeats itself.
By the time the baths full, the bottom half is cold. Is it really designed
to be this crap and is it otherwise a good boiler.
While i`m here, its making a right row when I turn the tap on, as if there
is an airlock in the heat exchanger. The auto air vent is open and I made
sure i filled it really slowly. Could my auto air vent be broken? Haven`t a
clue whats wrong with it.
Anyone have any ideas on how I can improve the thing, or is it the 9inch
angle grinder to the heat exchanger yyyyyeeeaaaaahhhh new combi here i come.
What you did gives combi's a bad name. The 80 is designed for small flats
with a shower only. You can rip it out and get a higher flowrate model. Or
if you have the space, install another higher flowrate model. Split the
combi's to do upstairs and downstairs independently and split the hot water
taps drawn off each. E.g., the 80 to supply the kitchen downstairs loo and
utility room and the more powerful job to supply the bathroom. Using two
will solve many problems and give backup if one is down.
Check the gas rating. A house can have 212 cu foot/hour max. You can go
over on peaks. To get the cubic foot consumption of an appliance divide the
Btus/hr by 1000. So your 80,000 consumes 80 cu foot/hr.
