There have been quite a few studies on the lifetime emissions of ICE vs BEV showing that overall BEV produce less emissions. This was a whitepaper published by The International Council on Clean Transportation last year. A global comparison of the life-cycle greenhouse gas emissions of...

Are those valves on the manifold directional requiring water flow through them in a particular direction? I see an arrow on the side of one of the valves in the photos pointing into the manifold, and that half of the manifold looks to be the incoming hotter water side if the guages are...

Could it be that there is other network reinforcement required by SSEN along with unlooping in order to provide enough power with the charge being related to that? When I got my supply unlooped my DNO stated that there would not be any additional reinforcement of their network required and the...

Its not £250 for the PCB in this case though, that was the price including fitting by a RGI.

I had f61 error on my boiler a few years ago and it was down to a PCB fault. £250 sounds entirely reasonable for someone to fix the problem. In terms of the actual fault on my old PCB it was a common issue of the switch mode power supply output electrolytic capacitors having failed. The DC...

I put a TV on a chimney breast above a log burner after some experimentation with bits of wood and a thermometer to determine how effective a mantel would be and deflecting the hot air stream. Turned out a 6" deep mantel did a great job of pushing the hot air out far enough to leave the TV in...

My only thoughts on induction hob efficiency would be there is some energy lost from the power electronics running the rings getting hot (my induction hob has cooling fans for the electronics), but I assume those losses must be less than the unnecessary heating of the extra mass in a...

Some time ago I experimented with the real life load of my induction hob and double oven using a clamp meter. The situation I tested was 4 pans of cold water on the hob then turning on all rings and both ovens within a few seconds of each other. The pans come to the boil very quickly (a few...

I don't think they are, which is a shame as they are LED lamps built properly. Suppose theres less money to be made for manufacturers selling lamps that last rather than need constantly replacing...

Need to get yourself some philips Dubai lamps, there are more LEDs run at lower current which improves efficiency and will last longer.

A shower permanently turned off is also a legionnaires risk, at my work place they have regular timetable of running all taps/showers throughout the building to prevent little used outlets being a risk.

Wouldn't removing the shower and capping the pipes then leave dead legs with no water flow that could be a legionnaires disease risk?

You could try using a product called 'algon'. It's basically strong vinegar and kills algae, dilutes down and can be sprayed and probably brushed on.

Paint the outside walls of the house white - it will help reflect some of the suns energy away and reduce the heating of the walls.

People gave you alternative solutions, but you seem to be dismissing them and appear to want someone to tell you its ok for your builder to do it wrong. :confused: You asked for thoughts I gave you mine. But its your house, do whatever you want to it, I don't really care. :)

My thoughts would be the builder sounds like an idiot and I'd not want them doing work on my house. Why would them finding another idiot to say notching the bottom of joists is OK make it acceptable to you when you already know its not?

If its control circuitry rather than say an element thats failed in the oven (assuming its not just the clock needing setting) its possible it was already on the verge of failure and the power being switched off/on whilst work was done was enough to push it over the edge. Quite common for...

My supply was looped with my next door neighbor and I got Electricity North West to unloop it. My neighbors were about to redo their driveway and as a bit of futureproofing ready for EV uptake I made enquiries about getting our supplies separated before they did it. The supply came into my...

Is it possible for central heating water/inhibitor be contaminating the tank if somehow there is a leak in the heating coil within the tank?
