Hello everyone,
We are looking to buy a single-family house with about 200 m² (2,150 sq ft) of living space, which has an electric underfloor heating system from 1986. This needs to be replaced due to the costs mentioned by the real estate agent (around 800 euros per month!!) if we can afford it. What affordable alternatives can you recommend? We are very grateful for all suggestions and ideas! Best regards, annasascha

Today we were shown an energy certificate, but it dates back to 2013. Is this normal? Do these certificates last longer, or is the agent hiding something?

An energy performance certificate is valid for 10 years; the validity period is stated on the first page (at least on mine)!

Supposedly, only the windows need to be replaced.

In our opinion, unfortunately the bathrooms as well as the water heaters and the heating system too.
I can easily believe the windows need replacing. The bathrooms are probably "just" a matter of taste. Is there nothing about the heating system in the energy certificate?

We also considered installing a new underfloor heating system. Since the floors would need to be opened anyway, the bathrooms would have to be renovated as well. We have estimated the total costs at around 100,000, as we can only install the new flooring ourselves :-(

Because the purchase price is not a bargain, no bank will finance us including renovation costs of this amount. Therefore, we are thinking about how to keep heating costs low with minimal effort. However, we will probably not be able to avoid installing the new underfloor heating system...

@Energiepass: At least in 2013, the heating system was not listed, only the windows. Strange.

Is this an energy consumption certificate? As far as I know, it is based solely on actual consumption and does not provide information about the building’s condition.
Why was an energy certificate issued for a single-family house in 2013 at all? Was it sold or rented at that time?
If sold: why?

I believe that with the information available so far, it is difficult to give you specific advice.

Energy consumption often depends very much on the individual users. In my house, there was once a person living in 90sqm (970 sq ft) who had heating costs twice as high as we do in 170sqm (1,830 sq ft). She experienced extreme heat in her space, especially from a radiator in the bathroom; she eventually had a dispute with the meter reading company, but it was proven that she always turned the heating up to the maximum.

My house was built back in 1990, when energy consumption was not as closely monitored, and such astronomical consumption levels were not common.

I think you should ask for more details. Perhaps a different heating system upgrade, other than underfloor heating, might be more suitable for you. Nowadays, modern houses are also heated with air-source heat pumps or a fireplace plus an auxiliary heater, etc. If the house is otherwise well built, it should still be possible to heat it properly today.

You say it’s not a bargain..., so you might be putting yourselves under financial pressure. I would consider that carefully. General statements from acquaintances with some figures won’t help you much.

I am sitting here (finally) with a small flame in the wood stove, and that’s enough. Perhaps the fireplace or a chimney system could take on the main heating role?

More information would be helpful, and I would recommend hiring a professional to advise you on this.
