Indeed. Our system does the same, and ticks along at between 35 to 45. 47 on very the coldest days. No zoning. As you say, zoning another thing that in most domestic properties is all a bit pointless. Just keep whole house same consistent temp is probably best. Heating engineers should really...

Simply not true and we have neither of those things (either a well insulated house or money to burn) I can assure you, thanks. I think generally if you are looking to overhaul your central heating/DHW it’s another option that should be considered.

Night and day between gravity and sealed/unvented in terms of hot water pressure, for us….was definitely a worthwhile upgrade. Worth getting quotes for ashp as well if a viable option- as quotes will include the whole lot, getting rid of existing tanks, converting to pressurised system, new DHW...

Common misconception that combis are cheaper for DHW, for whatever amount of usage really. They aren't in our experience. Definitely go for weather comp as Notch suggests. We have an ASHP now but regardless of what heats the water, with weather comp the house is much more comfortable. Would...

Thanks all, seems like I might be overthinking the structural integrity side of things. I was going to use expanding foam around the edges to try and stop any draughts.

Hi all, I'll be redoing the flooring in my kitchen soon and I have some gaps in the existing floorboards where they have been cut/removed to allow for access to services presumably around the perimeter of the room. The previous kitchen installers just nailed 6mm ply over them, which I've...

Thanks madrab just wanted to make sure wasn’t missing something. I’ve ordered that set.

Hi all, I'm fitting a standard convector K3 radiator in my kitchen and Im going to replumb it so the pipes are chased into the wall rather than through the floorboards. Thus, I was looking for some equally bog standard corner lockshield valves to go with it (don't want TRV one side as will...

Ok. I wouldn't completely discount tray options simply on this basis then. As per above...nero's looks very nice. I installed a Bette tray in our last shower room. Ours is in a niche, but the style you want would be something along these lines...

I've done all of our 3 bathrooms so I wouldn't be put off DIYing any of it. There is a lot to it though so your 6 point to do list will be more like 20 or 30. Just consider everything you are putting in, so what materials you are using (so if you do go with tray, what type/material. If grout...

When you say wet room style shower, do you mean you just want a wet room? There is a big difference between this and a tray/enclosure. I’d start off by researching what is involved in the former perhaps if you haven’t already, as it definitely isn’t simple. Personally Id be looking at tray...

Some good points to consider- thanks

Hi all, Just checking- is this sort of 15mm pipe good for CH pipework in wall chases to prevent the copper coming into contact with the plaster...

Thanks madrab. That makes sense regarding the two EVs. I'll keep monitoring the tundishes. Seemed odd that it lost no pressure when the HW was off for a couple of weeks but perhaps the movement in the system and pressure changes are when it manifests itself.

Hi all, We have a sealed CH system with unvented cylinder (which is quite new, 3 or 4 years old). I've been monitoring the pressure gauge for a few weeks which I try and keep at 1.3 bar. It has needed topping up every now and again, and will lose around 0.1 bar every few days.Interestingly we...

Epoxy grout is next level for durability and crack resistance. Slightly more difficult to work with though, and more expensive. I've used a lot of different grouts but having now used epoxy for my hallway flooring and three bathrooms I'd not go back to cement grout. Might be slightly overkill...

Could be extensive, if for some reason your main flow and return pipework is undersized, or perhaps all your radiators are the smallest size possible and your gas boiler runs constantly at 60 to keep your house warm in winter. Probably not the case though. We only needed 4 or 5 rads changing (we...

Why would they not be, unless you needed such massive radiators that it becomes unfeasible? If the emitters are upgraded to match heat losses at sensible flow temps I don’t see why it would be a problem. Pipework diameter might be the only other consideration potentially. Our house is very...

Appreciating there will be a limit to what a particular building fabric can sustain in terms of lower flow temps and comfortable IAT if a house is particularly poorly insulated and draughty, but I think that the majority of properties would be suitable for ASHPs, if the emitters/heat losses are...

On a serious note, can you categorically state that they don’t work with respect to inhibition of formation of limescale deposits? Magnets can alter chemical compositions and numerous studies support this. The fact that there may be limited or no independent studies specific to these devices...
