Bungalow120 explanations, experiences?

Hi,
I’m new here.
Here is the post for my introduction in the forum:



My question:

HEATING

1. Underfloor heating: controllable in every room?
Question:
YES / NO (with reasoning or pros and cons)?

2. Planned air/water heat pump: Dimplex Splydro LAW 9IMR
Question:
Are there any experiences in the forum with this device? AND/OR which comparable devices would you recommend?

2.1. Maximum flow temperature: 55 °C
Question:
From what I have read so far, 55° is a high flow temperature, which requires/consumes a lot of power.
How should the flow temperature be understood?

2.2. Switchable pipe heater (2/4/6 kW) for heating support
Question:
I can still understand pipe heating for heating support, but what does "switchable" mean in this case? Does it mean that you can switch manually to electric operation "if it doesn’t get warm enough"? Or is this meant for domestic hot water?

2.3. Hot water storage tank 300 L with 3.2 m² pipe heat exchanger and flange heater 1.5 kW for thermal disinfection
Question:
Hot water storage tank = domestic hot water?
Then 300 L would be almost a bit too much, right?
Yes, I know it depends on the number of people, needs, and habits. Therefore:

[*]2 adults
[*]Wife (housewife) average per week:
2x bathing max 3/4 full (tub with max 200 liters),
1x shower max. 10 minutes
[*]Me (office job/so no dirty work):
shower every other day (each 10-20 minutes)
[*]Children: none yet, but 1-2 planned.

The other question would be, what is the deal with the
"3.2 m² pipe heat exchanger and flange heater 1.5 kW"?

2.4. Electronically controlled pump, 100L buffer tank and bypass valve to ensure the required heating water flow rate
Question:
100 L buffer tank is then probably for the heating water.
I have read that no buffer tank is needed for underfloor heating,
because the screed stores the heat...?

3. A wood stove is planned, which will be located in the living/dining/kitchen area.
Question:
How does the heat pump behave with the underfloor heating when I heat for a longer time with the wood stove?
Does the heating then switch off for this period (because the temperature is reached by the stove)?
If yes, is this in any way harmful for the heating/underfloor heating because it “rests” for a longer time?

4. Combination device or separate storage tanks for domestic hot water....
Question:
What are the advantages and disadvantages if you have 2 storage tanks instead of a “combination device”?
One advantage is clear to me: you save space in the heating room with the combination device.
Anything else...?

Thanks in advance!! for help and answers! (Sorry that it’s so much at once but these things are unclear and probably easy for you to answer)

It would be best to answer with the "numbering" so that we and the other readers can understand each other.

PS: For those who don’t read the introduction post:
It is a bungalow without a basement with a hip roof 30°.
Living area would be 120 sqm with an outer dimension of 12.5 x 11.6 meters.
Construction method would be solid. (36.5 cm bricks)
If you have further questions, feel free to ask or look it up.

Hi,

It's best to give the answer with "numbering" so that we and the other readers understand each other ;)

You forgot to write the possible points after the questions :)

........sorry, no offense intended, but it reads like a test ;)

Regards

Regarding 1: Yes - So that you can set the temperature individually,... Especially when the children's room is empty at first
Regarding 2: The heating system must meet your needs and your house. To answer this generally would be like looking into a crystal ball. You have thought about the required demand. Now provide details about the planned house and we could perform a heating load calculation,... of course free of charge. If you want to make a truly economical decision, go to a professional and have the sizing and type of heating calculated that fits your needs/house.
Regarding 3: Why should it be harmful? In summer you don’t heat either, right? If you can warm your place sufficiently with the stove (including the bathroom), you can turn off the heating completely. That doesn’t harm at all.

Greetings from Munich to Bavaria ;)

THANK YOU!
Regarding 1. OK. I'm just asking because I once read that you don’t need to adjust it there, but only at the heating unit itself. And if the heating is set properly, then the temperature in the house is fine anyway...(that was just roughly in my own words)
But I’m also in favor of regulation in the rooms. Thanks again for the confirmation.
Regarding 2. Details about the planned house can be found in the first post (link). Or should I write that in again?
Or what other details are needed?
This heating system (see above) has already been offered by a heating company. That’s why I’m asking about experiences.
Regarding 3. .....embarrassing... Sorry... that’s obvious :) THANK YOU!
(sometimes you just have tunnel vision when you're dealing with too many things)

Hi, you forgot to write the possible points behind the questions :) ........sorry, not meant badly, but it reads like a class test ;) Regards

Hi, ...by the way you get 0 points... no suitable answer. Just kidding... yes you are right.... :) I just tried to simplify it somehow... because even when I read in the forum I sometimes can't assign the answers...
