If the motorised valve to the hot water cylinder is open it should then send a signal via the internal micro switch to the boiler. You have a grey and an orange wire going into the valve. The micro switch completes the circuit on the grey and orange wires. It may be easier to swap over the whole actuator head but sometimes you can tickle the micro switch to get it working. I have seen them clogged with debris.

yes

At least you noticed it before chopping through it.

yes if you can use the kind of fixings they sell for external wall insulation that will be fine. Otherwise you have to drill plug and screw them in.

Our pleasure, it is nice to know that you are encouraged.

It is a worry but it is all about managing and pricing. You can have a good life but try not to win jobs on price. Most people want a good job and that is only ever done by people who care. If you communicate that to your customers they will employ you because they like you.

@@SkillBuilder thanks for the advice mate👍 I’ll keep that in mind for the future atleast I can say now I have had a tip from Skill Builder 😀

Hi Steve I understand why people say a drum sander is best but they are expensive. You can get a belt sander with a stand and rest, or make one and it will do the same job but it can also be used for the face as well as the end grain. ukposts.info/have/v-deo/f6aFqnt5iGd91Kc.html

That is a standard floor construction and he is right to say that it is load bearing. If you have photographs of the construction this should help but it should have been done under building control and inspected.

No but they are similar and it is fairly easy to work it out.

@@SkillBuilder Thank you

@SkillBuilder mine is Grohe and has a bellow

it is a fairly standard industry test and so long as all of them are the same we are fine. You could go on perfecting this test for a long time.

Thank you for sharing the content, the more people who see it the better,

Hi David It is very easy to top up the expansion vessel. You need to drain a bit of water out of the system so the needle is on zero. Pumping up the expansion vessel is the same as pumping up a bike tyre. You are looking for just over 1 bar. If there is spare capacity in the system the expansion vessel will not have to work against a dead head of water. You only need to drain a bucket full out of the system. When the expansion vessel is topped up you simply repressure the system from the filling loop.

@@SkillBuilder Many thanks for the information, that's very good of you.

There will be people who want to lower their carbon footprint (dubious proposition) but many people will only undertake green initiatives if it doesn't cost them money. Nobody controls the narrative on this so saying it is a false argument is your opinion, which has no more weight than anyone else's.

@@SkillBuilder dubious proposition - go on? Nobody controls the narrative but you do set the titles of your videos. It is a false narrative that heat pumps should be cheaper, that’s not the intent. The intent is to provide a way to use electricity to heat homes more efficiently than resistive heaters can. This then enables a realistic move away from fossil fuels. It is not supposed to be cheaper, it’s supposed to be cleaner. If it comes out approximately the same cost then great, but it’s a false premise that it should be or will be cheaper. I’m a chemical engineer with two decades experience in power and energy. Not all opinions are equal.

@@paulharrison2325 Hi Paul With your long experience it would seem to me that you could have framed the argument a little better but never mind. Let us stick to facts Heat pumps are marketed by many as being more economical to run than a gas boiler so the question in the title is entorely legitimate. Dubious propostion-: much of our electricity is produced by gas fired power stations and moving more people off mains gas onto electricity at the rate proposed means that a great many heat pumps are (indirectl) gas powered. Heat pumps need to run 24/7 to gain efficiencies so that means they are running three times as long as a gas boiler. Heat pumps are not as flexible so a sudden rise in temperature, when you might not need heating, is better dealt with by a gas boiler. Scrapping serviceable gas boilers and replacing them with heat pumps carries embedded carbon. It takes several years to show any carbon reduction. How many heat pumps do we have to install to make any difference to our carbon footprint? Insulation is by far and away more effective at reducing carbon, it can be done a lot cheaper and carries on paying back for much longer. Read Deiter Helm on renewables. He holds the opinion that we are pissing in the wind with most of this stuff and it is a distraction. The money should be spent elsewhere. It is our money in the end and the government is squandering it on virtue signalling. Thanks for the debate by the way.

@@SkillBuilder I live in North Scotland electricity region (the bit above Stirling), a quick glance at National Grid ESO App' will show that my electricity more often than not is zero CO2 wind and hydro generated. It's an education just to see where electricity for each generating region in UK comes from, quite often gas is not top of the list. As I type East England is 54% wind, 34% nuclear and 13% gas. S.E England 24% wind, 6% gas, and rest imported from Europe... My heat pump is 'off' at present by my choice (it shuts down immediately, sitting in standby consuming 10W), when running it will shut down immediately the outside temperature reaches a specific value. When it ran took an hour or two to bring house ambient up a bit, but still performs well with a COP over 4, since installation the overall is 4.2. The UK fits about 1.5 Million boilers each year into existing homes these are to replace existing units not serviceable units, so a big opportunity to clean up the air a bit. It is anything but virtue signalling, if nothing is done then nothing will change and our environment will deteriorate faster than ever. Already this year the wettest 18 months since records began in 1836, with crops failing and sewers overflowing. If renewables are pissing in the wind then take a look at what China does as it pushes to dominate the World in renewables. Yes it builds coal generators, but it also has a plan to phase them out, it currently produces 30% of its electricity with renewables (enough for 400 Million people (30% of 1.4 Billion)).

Play it at half speed.
