Electric Heaters in new build home and lack of insulation

justwhat

This does not sound like it is right.
Are the heaters the correct size/output for the rooms? 
What does the temp get upto when you leave them on all day ?
What is the model of the dimplex?

If the OP wants help they really need to precisely answer the questions.

1)Make and model of Dimplex heaters?
2)If they are storage heaters do you have experience with using them?
3)Can you poke you head up in the loft and see thick insulation on the ceiling?
4)Does the house have a large open-plan area that difficult to heat or any vaulted ceilings etc as they can be a sod to heat especially with the recent cold weather

Most of these have been asked but not responded to Panda.

another question, how old is the house - if brand new it may well be drying out depending on the constructions. It can take a fair amount of time for all the damp to evaporate, especially in the winter.

Isn't MHVR a requirement for a Passive House?  You must have some sort of certification, surely?  But I think perhaps the builders can qualify as Passive House certified builders and then self certify what they build?  Perhaps you need an independent third party to look your house over and see if it really is was it says it is?

I think it's clear the OP passive house statement was incorrect just a very efficient EPC A 92 in theory if the local small scale builder has built the property to spec. That's been cleared up already.

Everyone who's saying "get gas CH" or "fit a log burner" is missing the point. Even if the OP did this, at considerable expense, they'd still have a house that leaks heat like a sieve, would still be expensive to heat and would be worth considerably less than it should.

They need to get the developer to find the faults with their year-old new-build and fix them. Anything else is avoiding the issue.

Agree with this completely, any form of heating is going to end up being expensive if the house isn’t retaining that heat. Installing any kind of new heating system without resolving the heat loss issues first would just be throwing good money after bad.

The heat must be going somewhere, first step is to determine exactly where and why.

Unless the developer gets a move on and agrees to cover the electric bill or covers a rental while they rip the house open to fix the problem, they will need a way to stay warm.

They have their heat one room plan in motion. 19oC locked door apparently.

Hopefully a big easier til mid December less minus dips.

Now that the weather has turned cold, an ideal time to get a thermographic survey done. Whilst it will cost a few quid, it will provide evidence of where the heat loss is. Depending on how the complaint goes with the developer, the cost of the survey might be claimed back.

This may be clear to you, @MultiFuelBurner, and I think you must be correct, but is it clear to the OP?  I can't find any statement from them to that effect and manifestly they were expecting better performance than they are getting.
