Junkers Bosch in home heating

Junkers is the historic brand of the Bosch group dedicated to home heating. For decades it has designed condensing boilers and domestic hot water systems built to cut consumption and last over time. Choosing Junkers Bosch means relying on a wide service network and a supply of spare parts that keeps every system easy to maintain over the years.

Why choose a condensing boiler

The condensing boiler recovers the heat from the exhaust fumes that a traditional boiler would waste, so it heats the rooms and produces hot water while burning less gas. On home systems the useful output generally ranges from 24 to 35 kW, enough for flats and terraced houses. The result is steady comfort with lighter bills and lower emissions.

What power in kW your home needs

The power is chosen according to the floor area, the insulation and the number of bathrooms to serve. As a general reference:

  • 24 kW: flats up to about 90 m² with one bathroom.
  • 28 kW: homes from 90 to 130 m² with average hot water use.
  • 35 kW: large homes or those with several bathrooms and higher hot water demand.

If you are looking for a compact wall-mounted model, consider the wall-hung boilers, the most common solution for homes.

Domestic hot water always ready

Many Junkers Bosch boilers are combi units, so they handle heating and hot water together. When hot water demand is high, or you want to separate domestic hot water production from heating, you can add a water heater: you will find traditional water heaters and heat pump water heaters, more efficient on electricity use.

Compare with the other heating brands

Before choosing, it pays to compare several manufacturers on quality, warranty and spare parts availability. Besides Junkers Bosch, our catalogue includes brands such as Bosch, Vaillant, Baxi and Ariston. You can also start from the general heating category to find your way among the different technologies.

Heat pumps and hybrid systems

To cut gas consumption even further, a condensing boiler can be paired with a heat pump in a hybrid configuration. The system automatically picks the most cost-effective source according to the outdoor temperature and the cost of energy, a solution increasingly requested for renovations.

Tax incentives and savings

Replacing the old boiler with a condensing model may qualify for tax incentives where applicable, such as reduced VAT for renovation work. The conditions depend on the type of work, so it is best to check the current requirements before buying. You will find the best prices among the current offers.
