We have a large lounge with the original parquet flooring suspended over a timber frame. Unfortunately there is always cold air blowing through the parquet flooring leading to heat loss and expensive heating bills. The flooring resides above the cellar in a crawl space. The cellar is open and...

So wires to 1 & 3 only? What is number 4 used for?

The missus has vetoed the DT90e purely on looks :( Looks like we'll be going for this one: Horstmann HRT4-B Digital Thermostat The HRT4B is a 2 wire thermostat: The exisiting Sunvic is three wires: I know the blue neutral needs to be blocked off. Is the red wire the common...

We currently have two Sunvic room thermostats which we'd like to change for one of the new TPI digital ones. The Sunvic is a 3 wire thermostat so what would be the recommended new thermostat (with TPI) to fit?

Does anyone know if the value head from a Honeywell 22mm interchangeable with one from a 28mm?

Is it a straight forward diy job to replace?

I just had a look. I have three of those. One is marked with 'upstairs heating', the other with 'downstairs heating' and the third with 'hot water' All three have a lever on the side. If I pull the lever it seems to wind something and then come back into the original position. That happens on...

This is the setup of the central heating: Two theromostats (one for upstairs and one for downstairs). Both linked into a digital controller which allows control of the central heating and water heating. The water heater is an unvented water cylinder. Two Viessmann Vitodens 100 work in...

Sorry, in my original post I stated "7.7kwh". The was wrong. I inadvertently entered a decimal when i shouldn't have. The actual reading was 77. The following readings were taken immediately before and after the holiday, before we switched anything else on or off. Reading before holidays...

sorry, was jet lagged when I wrote the energy usage. It is 427 watts per hour consistently. Someone has suggested is the consumer unit but I can't see how.

Thanks for the reply. The loft is massive and would make a lovely chill out area when I get around to it. Because I may convert it later, I asked building regs for their opinion and it would have to be 50mm. So I'll be able to fit in 50mm between the rafters, and then 80mm on top, or...

I'm looking at getting the loft insulated at the ceiling level. From the various threads I've read, it appears there needs to be a gap of 50mm between the tiles and insulation material in the eaves. Is 50mm the minimum value and is it a legal requiremnt? However as our house is over 200...

Lol. I didn't bother rounding

We're thinking of extending into our loft and would require new steel beams to support the roof and floor. However, we don't get on with our neighbours and have no doubt they will object in some way. The neighbours have already extended into their loft prior to us moving into the home, and I...
