The joists sit inside a single skinned Bungaroosh wall in Brighton. The wall has no cement and a low content of lime. Frankly the houses here are shocking! A mistake nearly all homeowners make is rendering their houses in cement mortar thinking that it will add strength to what is otherwise...

I need to change many of the original floor joists due to rot. Typically joists are wrapped in DPM using stable gun for example. I’m wandering if there’s a better way such as foil tape. Any thoughts would be most welcome.

Well, I guess the ridge is resting in the gable walls and some, albeit not enough support is given by two ashlar walls resting on two a pair of 2x (8x2) beams bolted together. Its not great and I eager to reinstate support the day I get the keys! Just hope the roof doesn't fall on my head...

Hey folks, Im about to buy a victorian terrace house with a gable to gable roof. The previous owner decided to remove the perlins and struts and make a non BC approved loft room! The Ashlar walls are supported by two 8x2 timer beams which have been calculated to be about a quarter of the...

Thanks DP, I have MV’s for the Ch and HW as usual. So the pump that drives the water around the primary flow and return boiler and tank isn’t powerful enough to drive water around the UF circuit, so the second pump is a booster. Have I understood it right?

Thanks, yeah the pump etc are supplied with the kit which is why I didn’t mention it.

hi there, So my CH is an Vented system. I want to install UFH into a new extension. Rather than plumbing into existiting secondary flow and return for rads, I’m told the best way is to create new flow and return control with its own motorised valve. To avoid the pumped return spilling into the...

Thanks so much for your reply Pilsbury. The ground for the most part is untouched. It’s 30 square meters. There was one drain which disturbed some ground. I’ve already spread the mot and am having to take some out because I’ve over done it. It’s a killer as I already compacted it. The screed...

Hi all, I’m in a quandary. My extension is 340mm from excavated ground to finished floor level. I will be installing underfloor heating so the order of materials from bottom up is as follows; Hardcore Sandbinding DPM Concrete slab Sand binding to level imperfections Rigid insulation Underfloor...

hi there, I'm putting 50mm of kingspan tp10 between the 8x2 rafters, 18mm ply ontop of the rafters then 100mm of kingspan tr27 on top of that. Confused as to where the Vapour control barrier should go. I guess on the underside of the tp10 between the joists. The only type of VPC that would...

hi all, Apart from the obvious difference, has anyone had any experience of fixing wall cabinets to both of these materials and does the 7.3n offer more strength in this regard. If not I'll save my money and go for the 3.6n's

Hi there, I'm going to put a bio ethanol burner inset into a granite plate which will rest on about three course of brickwork raising the floor of the builders opening of my fire place. The problem is that the burner requires 230mm of depth and the depth of the fire place is 360mm. The only...

Hello, I want to pour a path and have previously used 12mm ply with timber steaks used every 30cm. Due to cost I want to know if anyone has used a cheaper material like OSB? Love to hear

The usually open valve fitted to the bypass reduces return temperatures and means that well balances radiators will contribute to a return with a 20 degree diff from the flow. This optimises condensing which saves money, and it stops the boiler from cycling as often. Radiators also get...

Hi all, I have clamped a pipe thermometer to the common flow immediately emerging from the boiler. With a return temperature of 40 I still only get temperatures of 60 max on the flow with the boiler pemeprature set to max. According to WBosch a 15ri max temp ought to be 82. I bought...

I'm a little gutted to be frank. My ego would have quite like to him of itself as pioneering! So the improvement has exceeded my expectation. It's a must as far as i concerned. The lever's just useful for a quick check to see if the valve is active I.e a baggy lever.

Hi tony, You asked about the purpose and intended benefit... Before, when I had the bypass always open, the water passing from the flow to the return via the bypass would increase then mean temperature of the return thus causing the boiler to modulate prematurely, particularly when most of...

Awesome Tony, thanks.

Hi Tony, On schematic diagrams I've seen online it sometimes appears that the pump live is connected to the orange of the motorised valve. In that case it would suggest that the valve would remain closed until the pump stops, but I think what you said in your last paragraph is the case with...

Hi guys I previously thought that the balancing valve on the flow side of the HW cylinder was intended to ensure a shared flow the the HW and CH systems when they are both active, however, it occurred to me that the flow temperature through the W cylinder will affect the return temperature and...
