Viessmann Vitodens 200-W 19kW - a system boiler, regular boiler or combi boiler?

If you are considering installing a system boiler in your house or flat, then the Viessmann Vitodens 200-W 19kW boiler is certainly worth investigating.

For homes that have a higher-than-average demand for hot water and heating and for larger properties, system boilers are a more suitable option than the more popular combi boilers.

Combi boilers heat water on demand but the amount of water they can actually deliver to taps is determined by the mains water pressure, flow rate and power. System boilers instead use a hot water cylinder that stores and keeps water hot throughout the day. As long as you remember to program the times you want hot water and the cylinder still has water left in it, you should have hot water whenever you need it.

And, unlike heat only boilers that also require a cold water storage tank to work (normally fitted in the loft), system boilers don't, meaning they're quicker, easier and cheaper to install.

Is the Viessmann Vitodens 200-W 19kW system boiler suitable for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your gas bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

Would installing a Viessmann Vitodens 200-W 19kW system boiler in your home be a green choice? Let's look at the numbers.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Viessmann Vitodens 200-W 19kW was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".
