Gas boilers for heating with storage tank connection option
Gas boilers with a storage tank connection option are dedicated technical gas appliances for heating water in radiators in the home, with the option of connecting any storage tank or hot water cylinder. This water heating is carried out by means of a special three-way valve with a servo motor, controlled by the boiler's electronics.
When there is demand from the storage tank, this three-way valve switches the flow of hot water from the radiators into the heat exchanger of this cylinder (water storage tank). It heats the water this way until the sensor registers the required temperature, and only then does the three-way valve switch back to its original position and heating resumes to the radiators. This heating and water heating solution is suitable especially where there is demand for a higher water draw-off. For example, a family of 3-5.
These water tanks can be of any size, type or construction. It is also possible to use an original or old hot water cylinder. A requirement for all water storage tanks or water tanks is the ability to insert a temperature sensor from the boiler, which allows this water temperature to be measured. A circulation loop can be added to almost any storage tank, ensuring that hot water is always available, so there's no need to run off cold water first.
Frequently Asked Questions
- What does a boiler "with storage tank connection option" mean? It's a classic gas boiler to which a storage tank (hot water cylinder) for heating domestic hot water is connected externally - the boiler itself does not prepare hot water.
- Are these condensing boilers? No, these are classic (non-condensing, atmospheric) boilers. Their efficiency is lower than that of condensing boilers, so they are suitable especially as a replacement for the same type in an older system.
- What size storage tank should I choose? Typically from 100 to 200 litres, depending on the number of people in the household and hot water consumption.
- Why choose this type of boiler instead of a condensing one? Especially for a straightforward replacement of an old atmospheric boiler with a new one of the same type, where no modification of the chimney or condensate drainage is required.
- Are these boilers still on sale? Yes, they are currently in stock, but due to tightening EU emission requirements the range is gradually narrowing.
