The house is more airtight than average and this may not have been fully calculated for as we use the CISBE standard air change rates for this property age band as does every other installer.

Cheeky f**king so and so claiming that every installer uses the “no glass in the windows” air change rates based on property age rather than attending site and surveying the property with their own eyeballs to pick a different figure.

@matt-drummer

If you would like, we can look at installing an EDLA08. However, we would not be able to change the unit again if the unit is not performing in the coldest months of the year as it would be going against the original design.

That sounds like a peace offering.

Given:

• You’ve since mucked about with the install (from their perspective) by adding the heat meter / changing radiators

• Our tentacled friends pay their lawyers more than their installers and have promised you absolutely nothing contractually as far as the end result is concerned

Perhaps “respectfully disagree with the assertion that every other installer uses age-default air change rates rather than surveying the property in person and selecting an appropriate air change rate, and respectfully disagree that there is nothing wrong with a heatloss calculation that bears no resemblance to there not being two living rooms etc” but take them up on that offer to exchange the unit for one that the available data shows is more appropriately sized?
