ᐅ Pellet Heating + Solar: Is the Quote Reasonable?

Hello everyone,

I am new to the forum and hope to get some help evaluating a pellet heating system offer.

My wife and I, together with my parents, have purchased a house with approximately 400 sq meters (4300 sq ft) of living space. Currently, there is a 30-year-old oil heating system. The house is also 30 years old. An energy consultant inspected the entire house and recommended replacing the oil heating with a pellet heating system supported by solar heating.

The consultant prepared the following offer:

-- ST PARADIGMA wood pellet boiler Pelletti III, 30 kW nominal heat output, 9–30 kW
-- Pellet storage bunker
-- ST PARADIGMA Aqua package for hot water generation
-- PARADIGMA solar station STAqua single-loop solar station
-- Underfloor heating in the bathroom

All together costing 42,972.05 euros

From this, a grant from BAFA of about 7,800 euros will be deducted

So the actual costs would be around 35,000 euros

Originally, the heating installer’s first offer was around 49,000 euros (before the BAFA subsidy)

I would really appreciate if someone could help me assess this offer. I am also open to completely different ideas :-)

Thank you all in advance!!!!

Best regards ;-)

The offer must be considered in relation to the existing property – which we do not know. Therefore, even an expert likely cannot provide an answer.

Just get a second and a third quote. Only then can you really compare. Without that, you have no basis for comparison and no way of knowing if it’s appropriate.

There are certainly other alternatives, such as a gas condensing boiler or a ground-source heat pump.

If an energy consultant already comes up with specific manufacturers or even particular devices without being a mechanical, electrical, and plumbing (MEP) engineer at the same time, it creates the impression of a certain bias. ;-)

Best regards

Thank you for your responses.

We were also offered a ground source heat pump, but the payback period was too long and the offer was generally too expensive. The energy consultant doesn’t care which manufacturer or heating technology is used. At first, we favored the ground source heat pump, but unfortunately, the offers were not very good. Additionally, we would have had to install underfloor heating throughout the entire upper floor afterward in order for it to work effectively.

Edit: There is already underfloor heating throughout the entire ground floor!

Perhaps there is someone here who has already installed a pellet heating system and could share their experiences?

Hello,

we have a pellet boiler from Windhager and are very satisfied with it. Cleaning the boiler is very easy and can be done by myself. It produces very little ash.

In our system, the boiler heats the domestic hot water and the underfloor heating. We do not have any additional solar thermal system.
