The Worcester Bosch Greenstar 36CDi Compact Combi Boiler

There’s enough power to provide central heating and hot water to a typical 3-4 bedroom home.

So, if you have a large family with multiple bathrooms, then you won’t have any issues using this 36 CDi compact boiler.

If you want some figures to back this up, then the 36CDi has a hot water output of 36kW with a flow rate of 12.9 litres per minute.

Add to this the high-efficiency central heating output of 24kW, and you’ve got yourself a bit of a beast.

The 36kW makes it ideal for homes that use lots of hot water every single day, usually at similar times. For example, two showers running in the morning as the family gets ready for work/school.

If this output sounds too large for your home, you could view the Worcester Bosch Greenstar Si combi boiler or the best combi boilers 2023.

Worcester 36CDi Boiler Usability 

The way you operate a gas boiler has become more and more critical in recent times.

The introduction of the Boiler Plus regulations in 2018 has set new standards for all combi boilers.

In effect, every combi boiler must have controls that let you either hook it up to a smart thermostat, alter the water temperature based on room temperature, alter water temperature based on the outside temperature, or convert your wasted flue gas into energy to heat your water supply.

Combi boilers only need at least one of the above controls, and the Greenstar 36CDi is compatible with smart thermostats.

You can choose any thermostat on the market, or stick with Worcester Bosch and go for their Wave product. You can also use it with Hive or Nest smart thermostats.

Regardless, smart thermostat compatibility means you can control your boiler remotely.

There will be an app for you to use, and you can alter everything from the temperature settings to the schedule – it’s so convenient.

Of course, there are manual controls on the boiler as well.

Just pull the front flap down, and you’ll see a large display with various buttons.

They’re all clearly labelled, and you can adjust the temperature, set the boiler to different modes, and see any warning lights.

Your Worcester 36CDi compact boiler will also come with a manual in case you have any problems working any of the above controls.

All in all, we found the Worcester Bosch Greenstar 36CDi to have very easy-to-use controls.

As a result, it’s a boiler you can operate without any stress at all.
