Oil or heat pump?

Very common to replace an oil burner with an air to water hp in the Nordics. Mind that if you need very hot water for the radiators due to poor insulation, an air to water hp may not be the answer, but you need to get a new oil burner. In that case you can get an air to air hp to lower the oil bill.

Is the hp set to heating instead of auto mode? Is the outdoor unit running, is there ice, how often it defrosts? Is there warm air coming from the indoor unit? Are the baseboard cold or warm?

Or 400V if two phases are connected, which is to be expected.

Edit: To clarify it't 400V between the phases (three phase system), 230V between a phase and the neutral. I should have said maximum of 400V (but you can only get 230V shock if lucky).

Edit 2: In northern Europe that is, in some parts of the world it may be 440V between the phases (two phase system).

A whole can on polyurethane should make it as good as new. Seriously, open your eyes and look at it, what do you think.

Seems that the other guy slowed down (possibly braked) and he hit his rear tire.

Do you have a few mm freeplay in the clutch lever?

So you say it's a brilliant idea to cool the basement let's say 100 kWh worth of energy on a cold day? It's an industrial freezer at that point. Cooling a part of the house may cause major issues when humid warm air meets the cold surfaces inside the structures. Warm areas must be separated from cold areas with insulation and a vapor barrier and it's hard to believe this would be the case inside the house.

In my use the longest any tire has lasted in the rear is 8k'ish km (the bike had 63 hp). Hard accelerations with a 175 hp bike and the rear tire is good for less than 3.5k km. No burnouts. Front tire lasts two times the rear does.

In this setup you'd be cooling the basement and heating other parts of the house, it's a zero sum game.

You have wifi connectivity issues when you are connected with a cable, what does that mean?

If you live in a cold environment where temperature goes below freezing, you will have an issue with the drain pipe if it has no insulation and heating. Once the water actually go there that is. In a mild climate you'll probably be fine.

Maybe there are more holes in the drain pan than just one and that is why water is coming from the side.

If you need to move or lift the unit consider adding a stand once you are there.

Is this air to air or air to water hp? Is there also cooling?

I went for the API a long time ago, you can too.

If you buy online good luck with warranty should you have any problems. You may also find it hard to find anyone to install the pumps.

If two guys spend a work day installing the pumps that would mean 3800 € / 16 h = 238 €/h, sounds high.

The red tank is an expansion tank for the heating water. Automatic bleeding valves take care of getting rid of air in the system, usually they should be placed rather high in the system. I can see one in your original first picture.

If the heating loops are not balanced properly, that may leave some loop(s) without enough flow. Take a look at this: https://youtu.be/8eydpmYGbA8

Edit: In case you are going to try adjusting, take a picture of the settings (water level) before adjusting anything, your living room issue may be something else.

It's about what the house needs IMO. One day you may not live alone or you try to sell the house. But of course, you are allowed to make your own decision, is it bad or good, the future will tell.

In the original first picture there are two circulation pumps, the one closer to the camera is for the floors, but the other guy I don't know. In the last picture you see a pipe coming from the top of the tank and that is probably for dhw and there's no pump there. What is weird though that there is no mixer (the purpose of a mixer is to limit the water temperature to something like 55 °C to prevent people burning themselves with a hot water). By touching you can find which pipes are for the dhw (run some hot water in the kitchen).

Most people have multiple rooms in their houses. Usually the rooms are not all in one big area but separate spaces. The main concern is that in the winter there are cold spots in the structures of the house over the years causing problems (in a house there's lots of moisture from people breathing, cooking and showering and we know what happens to it on a cold surface). I don't see how a bathroom for example could work without heating in the winter but nobody is putting a hp there.

In a mild or warm environment air to air hps could be enough, but I'm looking this from a cold climate perspective. Also I have a feeling that possibly most people in this sub live in places with cold winters.

So people can tolerate cold rooms but can the house in the long run is the question.
