Who is Sime and why choose it

Sime is a long-established Italian brand specialised in home heating, with a range that includes condensing boilers, thermal units and solutions for domestic hot water production. Italian manufacturing ensures build quality, easily available spare parts and a support network spread across the whole country. It is a reliable choice for anyone looking for a solid and durable product.

Sime condensing boilers

The heart of the range is the Sime condensing boilers, which recover the heat of the exhaust fumes to reduce gas consumption and emissions. Compared with a traditional boiler, a condensing boiler can noticeably cut the bill, especially when paired with smart thermostats and a well-regulated system. The wall-hung versions, compact and suited to small spaces, are also available.

Which power in kW to choose

A boiler's power is measured in kW and should be chosen according to the area to be heated, the number of bathrooms and the demand for domestic hot water. Here is an indicative guide:

• from 24 to 25 kW: small and medium-sized flats with one bathroom.
• from 28 to 30 kW: larger homes or with two bathrooms and greater hot water demand.
• over 32 kW: large houses, villas or systems with high heat demand.

If you are unsure about the sizing, it is best to rely on a technician, because the correct power improves comfort and reduces consumption.

Sime for home heating

Sime solutions are designed for the heating of the home through radiators or underfloor systems, with stable output even on the coldest days. The wall-hung boilers range is particularly appreciated because it combines small dimensions and high performance, ideal for replacing an old generator.
