Here's how to equip yourself ... without breaking the bank!

[Econergy]

Hello again,

I cannot agree on having to increase the number of nuclear power plants to cope with the evolution of PACs

You simply forget in your comments that the number of direct electric heating installations is constantly growing. It represents around 40/45% of the heating park.

If these 40% were transformed into heat pumps of all types, we could roughly divide by 3 the production of electricity at the power stations, which would compensate for the replacement contribution of fuel boilers in heat pumps.

In partnership with a competent dowser, I work permanently on PAC solutions for groundwater or underground river. The results are very astonishing. Fuel consumption was divided by ... 5

We must not take refuge behind a piece of writing, we must look at the problem globally, taking all the parameters into account.

Really?
Vivrelec I thought it was a scam from the past ...

For the rest, I quite agree.

By the way, do you know that to make an energy balance of a house (DPE) you have to correct the electric kWh by 2.58? So any heat pump with a COPA less than 2.58 is equivalent to a conventional boiler heating with an efficiency of 100% ... so assuming, to please you, an efficiency of 80% we would obtain a COPA of 2.1 min. it can be done ... to see the reliability (do you know a lot of fridges currently sold that last 20 or 30 years?)

[Econergy]

I did not say that the jet was the cause of everything, but it is part of it. If you read what I wrote correctly, the problem lies with the overall and real efficiency of the boilers.

I installed my first heat pump in 1979, it is still in operation. maintenance cost: 0

Not a single intervention. Those who advocate an interview, will tell me what they maintain on a CAP. Do you maintain your fridge?

The proper functioning, efficiency and longevity of a heat pump is totally dependent on the sizing calculation and the design of its technical environment.

What use are observations if they are based only on personal feelings that do not take into account the reality on the ground?

I follow very closely the consumption of all my customers, if the results were not eloquent, I would have changed jobs a long time ago.

Uh sorry but I can't believe it for a second ... no leak, no compressor change in 29 years? No refrigeration engineer will believe you ...

I hope I'm wrong but could you tell us more? Make, power, type ... Some pictures maybe? Here and your own installation? How do you heat yourself? Photo report?

Not a single intervention. Those who advocate an interview, will tell me what they maintain on a CAP. Do you maintain your fridge?

No, but a fridge does not last 20 to 30 years ... well, not those of now ...

Don't worry, it's okay, I'm used to forum or generally gravitate Internet users who believe only their own speech.

They cannot imagine that there are other truths than theirs.

If there was no client confidentiality to respect, I would give you his contact details right away. There are also others installed in 1980/1981 / etc .... which still work without having had a single maintenance.

A fridge fluid leak cannot be triggered on its own. You need a cracking solder or a leaking fitting. Without it, the fluid cannot pass through the copper.

Precisely, if you question refrigeration specialists who have experience, they will confirm that a compressor can have an unlimited lifespan, as long as it operates in good conditions.

90% of refrigerators that go into the trash have compressors in perfect working order. They are replaced because the door seal or the thermostat is screwed up, because you can no longer see it, or because the kitchen is being replaced.

This is the reality. And if a compressor needs to be replaced, that's not a problem, neither technical nor financial.

Don't worry you're not on one forum blablateur ...Here we do concrete as much as speeches... Do a little research to convince yourself: there is more practice than theory. And we are a lot of technicians ...

Confidentiality is a rather "small" excuse, don't you think? And you don't answer a photo report from your own installation? Isn't that confidential, is it? Here is ours (in part): https://www.econologie.com/forums/chaudiere- ... t4589.html

"Unlimited" and mechanical lifespan... it does not mix well then in thermodynamics even less ... You can perhaps say that on forums neophytes but not here where many are technicians or engineers ...

[Econergy]

I realize that the background of the characters of forum do not vary much from one forum to the other. It's so true that not for a single moment can you imagine you've got it all wrong.

I have passed the age of sterile speeches. I decided not to appear on this anymore forum which does not have the merit of housing characters responsible for their writings, and who openly allow themselves to treat others as liars.

It's getting serious.

But before I leave, I'll take the liberty of asking my client's permission to give his phone number here. But given the relatively twisted state of mind, one can imagine that you are pretending that it is only a bogus phone. But that remains your problem.

This will show everyone how certain Internet users, of which you seem to be a part, think they are lords of a bygone era.

hello, about this:

You should know if you have experience, that the electric heating only consumes the winter, the heat pump all year round, so your ratio of division by three I do not agree in addition to that the big peaks of electric conso that happens not in winter but in summer precisely because of all the PACS.

then with your 25 years of experience, you should also know that a lot of people make sanitary water with fuel, so so is it, even if it is a little less consumption than in winter with heating.

Alright, guys, better relax, as much as the boiled water from the CAP ...

I found a whole new way of heating ...

Le forum econology, it heats up, it heats up, summer and winter

I think you are both right, but from different angles.

Heat pumps alone are not as efficient as thermal solar panels, or good heating with wood, or even fuel, at least from an environmental point of view.

On the other hand, a heat pump can be combined with thermal solar panels. There is the best. A heat pump works with a free "cold" source already at 35 °, to increase to 80 ° sanitary water, the COP of the heat pump must be 7 at first glance ...

For the electricity of the CAP, it would obviously be renewable ...

What do you think ?

PS: Le modo (Christophe) and Tigrou have self-built a thermal buffer concept that stays within 30 ° C all year round (correct me if I say anything stupid). Mounting a heat pump on it would provide sanitary water for peanut in electricity.

It's getting serious.

What is especially serious are the storytellers on the internet who proclaim themselves specialists when they are only "ecoloportunist" importers ... I am not targeting anyone but it (largely) exists ...

What does it cost you to show us some pictures of YOUR personal installation? On the contrary, it would have advertised you for free and intelligently ...

Remundo:

a) I have nothing self built, I just repaired and optimized (a little) the thing

b) I have already thought about installing a water-water heat pump, the advantage is not to obtain cheap energy (the use of the heat pump will cost more than a direct exchanger) but above all it allows to improve (almost double) the range of use of the thermal buffer which is almost useless for DHW below 30 ° C. I thought about it but it is not for tomorrow (investment, gas plant ...) ... in the meantime I will use my deom
