We just got our first electricity bill for the month of February for our house in Sweden. We've left the ground source heat pump system set to 18c, and it has used an average of 29.5 kwh/day to heat 240 square metres. That is (by my reckoning) incredibly efficient. 

 

29kWh/ day is excellent. Our our air source heat pump does double that at current temperatures. This year, we’ve run our system bivalent. ASHP when it’s mild, and HVO (biofuel) boiler when temperatures drop and ASHP is less efficient. It’s worked well: https://myhomefarm.co.uk/going-bivalent-ashp-hvo

Hello

 

As part of my industrial design course, I am currently looking into indoor air pollution. I understand that air quality is a concern for many of us, so I aim to generate a solution that helps to provide cleaner air for our home environments.

A big part of designing new solutions is understanding the problem from the user perspective. Hence, it would be very helpful if you could answer a few questions about your experience with air quality at home. I look forward to gaining insight through your responses.
 

Questions:

1. Is indoor air quality something that you think about often, or that impacts you on your daily life (or that of your family members)?
2. Do you take any measures to try to protect yourself or family members from poor indoor air quality at home ?
3. Are you particularly concerned about any individual home pollutants?
4. Who do you think should be responsible for improving the quality of the air in your home (if anyone)?
5. Do you think more education about indoor air pollution is needed?
6. Would you benefit from a service that highlights low polluting home products ? How would you use this information?

Thank you,
Aaron

1. Yes.

2. yes

3. yes (cleaning products)

4. we take in this responsibility ourselves 

5. Yes

6. no

We’ve gone down the air source heat pump route.

You might find this interesting, because we share how and why we chose an air source heat pump to heat our home, and discuss some our experiences with installers.

You can the check out our installation experience fitting an air source heat pump and new water tank in our Victorian farmhouse.

Air source heat pumps are really worth looking into.
