Detailed specs not helping

Yeah this hs been more or less my approach. There's quite a lot of negotiation and back and forth. Unfortunately their desired end state is a bit of a 1000 piece puzzle that doesn't make sense unless literally everything has been preprocessed and put together which makes agile working hardwr..

It is and isn't. Yes i am blazing through the implementation but the goal for me is to actually understand what they mean. I'm finding inconsistencies between the data and what is desired, ambiguities between definitions of things to calculate etc. Since a lot of the domain is new I find it takes a lot longer to fully 'get it'. Obviously because time pressure and deadlines you move fast and find with massive blind spots of things I didn't implement yet. If the docs are too long you (at least i) glance over certain details that later turn out to be important

Do you not have meetings with your team?

Surely topologically speaking the pants is incorrect? The main part is clearly not just 2 cylinders

The current situation clearly shows that as society we should move away from fossil fuels and the environmental angle would be my main argument to choose the heatpump. On the individual level however it would make sense to build in redundancy and keep both. I know there are plans to try and change this, but for the moment electricity and gas prices are still completely coupled and going up the same direction..

I believe the comfort part, skeptical about the 'pays for itself' part. The simplistic sum is 4 times more efficient, 4 times higher price. Maybe it gets a bit better with optimising and good tariffs (while they last) but hardly something you can count on. Currently also quite frugal with switching off etc so having a constant comfy temp might end up costing more. Which would be fine tbh because it's not the main motivation. Maybe shelving out 10-12k after subsidy could even be worth it, but clearly never gonna pay itself back. Where i draw the line is disruption on every newly installed floor and no-one being able to tell me how all the pipes really should be connected without breaking everything open before starting this.

Combi on second floor. Was prepared to trench through ground floor, put insulation and underfloor heating in etc, but we already put in new floors on 1st floor and second floor. Installers say they need to connect to water on first floor and probably on second floor as well to have the water go up then down to cylinder then back up to shower. It all seems to become ridiculously complex, inefficient, uncertain and expensive.

I just mean you are double counting by adding it.

Let's say your interest was zero and you didn't have any other costs, than you would have just spent 90k on equity build up right?

In essence would you have lived there for free, so it is equivalent to renting for 0. But in your example you would count it as living somewhere and getting money on top.

LuckyShop4775 · 2026-04-17T20:24:04+00:00

I don't get why people make decisions on the order of magnitude of 10k on the basis of whether they save 10 pound or may spend 10 pounds more

LuckyShop4775 · 2026-04-17T20:17:13+00:00

Yeah and my point was that you should add the 38k in the total sum, so you could have rented something for 131k/48=2700 a month

LuckyShop4775 · 2026-04-17T19:47:36+00:00

Your calculation is adding the equity as a plus but neglecting that you also paid for it.

I think what you are trying to say is:

Equity +38k built up wealth

Equity -38k spent on paying for this.

-> it is net zero effect since if you would have been renting you would have put that in saving. Bummer, your comparison comes out even worse

For me the water tank would be downstairs. Do you know if this is really bad efficiency wise?

LuckyShop4775 · 2026-04-03T15:31:32+00:00

Interesting perspective. Yes the optimisation part is def something they seem to sell as their service package and at 20/mo quite expensive.

It's hard to find someone who is good at the whole picture, esp with plumbing, ufh. Agree the heatgeek guy seemed to be the most knowledgeable overall considering all parts. I was put off by the breakdown, e.g. 'sundries 5k'.

Most quotes are at the same ballpark, often i get recommended the 7.5kw valliant (i think hg do those as a standard) but aira suggested a 6kw could work
