Why buy a condensing combi with all the benefits of cost cutting, to fit a secondary loop system which is proven waste of money, people often complain saing am wasting gallons of water before I get hw ? 1. you are not wasting water, there is still the same amount of water on this planet as there was on the day of creation(fact, check it out) 2. water being on a meter or rates costs less than 1/1000 times less than wasting gas; ie run your tap for 30 seconds of cold water to get hot water at 10ltrs/min costs you 0.001p if you use a pre heated gas boiler you get hot water after 10 seconds using 0.01p of water but you have pre burnt 10p of gas, water will never run out but gas will

Apologies in advance for what is probably a dumb question, but with the open loop system, can i assume your rads upstairs are 'on' whenever the UFH is on?

That is correct. The system is always on covering any heat loss that may be happening. Keeping flow temps low.

Great video, exactly what you said, a lot of us old sole traders out here waiting to take the step over to ASHP. Interesting to see how you are tackling it all. It looks like Viessman have taken a lot of the ball ache out of these installations by the components doing everything you need them to. I assume its an expensive lot of kit but it looks like they make an installers life a lot easier and that can only be a good thing for us all. Really smart looking job, well done. Look forward to follow up video, thanks.

@normanboyes4983Ай бұрын
Very nice job. Interested in the Viessmann design side of things because this is crucial to success, who did the actual heat loss calculation - did Viessmann do that themselves? I ask because it is such an integral part of the design process and all the downstream MWT and emitter sizing results from it. On the bracketing of the external primaries - yes, external pipe support (around the primary pro) does not look as good but Munsons are effectively conductive bridges to the brick wall so not as thermally efficient. Finally, is the homeowner up to speed with fine tuning the weather compensation (curve and level)going forward or are you intending to tweak this remotely for them? Thank you for sharing, it would be good to get an update post 24/25 winter, in terms of system performance and customer satisfaction.👍
@loving-plumbingАй бұрын
@@normanboyes4983 so this property did have a heat loss carried out by myself, Viessmann as well as full SAP calculations. Viessmann actually provides some really good emitter sizing software as part of the umbrella scheme. It's more difficult with the underfloor. Especially with different floor finishes. Only time will tell. I'm looking forward to the winter ❄️. My main concern is that it's too hot 🥵
@normanboyes4983Ай бұрын
@@loving-plumbing I understand your concern but - keep the faith. It’s all about design and you and Viessmann have done the necessary. I strongly suspect it will perform absolutely fine once the curve is dialled in, getting the curve as ‘lean’ as possible is key. My experience based as a user of a gas V200 in an existing build. I changed quite a few rads to better match heat loss at reduced DT. It’s an all rad system, all TRV heads are off and in a box and I have no internal reference - pure weather comp. I deployed half a dozen bluetooth thermometers around the house while I was dialling in the curve - I have no overheating anywhere in the house we have never been so comfortable (40°C flow at -2).

@@normanboyes4983 that's awesome news. That's how I initially got the curve set. I deployed some thermostats also. I definitely dialed it down, which I guess is a good thing.

@@stevewells2536 it worked out that way for me really because the underfloor heating the client requested was designed at the same temperature. In reality the underfloor heating should be more like 30c -2. Those aluminium panels at 150mm centers aren't the best. If I could have got 100mm centers in I would have probably used a mixer to lower the Temperature. Either that or upsize the rads even more. It's worth doing the maths 👍. Thanks.

Thanks this is a really nicely done video. Small question is it better to do the flush or power flush before installing the new boiler or after. Just wondering if it is done before (using the old boiler to heat it up), the sediments in the pipes and radiators won’t go through the new boiler
@markcostello27343 ай бұрын
Something to think about - I always thought a plate heat exchanger should be piped countercurrent Eg boiler flow top / boiler return bottom - system flow top system return bottom Just think of a combi plate heat exchanger - mcw and boiler return are together as are hot out and boiler flow If you leave it like that the flow to the system will be at the boiler return temperature ie 20 deg lower then you require - plus the temperature degradation loss To quote Andrew Millward - hope that helps 😂
@loving-plumbing3 ай бұрын
I'm pretty sure it is piped that way. So each side is opposite. But the flow enters the bottom from the boiler. System flow leaves from the top. I don't believe it makes a huge difference which way round it is installed but could be wrong. Thanks
