The combination boilers
are designed to be an all in one unit which produces hot water for taps and
central heating in order to cut down the use of storage tanks or cylinders,
thus occupying the least space required to house the boiler. The Combi boilers
are one of the most popular choices for keeping homes warm in winters.
The boilers are
designed to operate using the water directly from the main supply that results
in stronger water pressure and ensures that you would never be lacking on hot
water again. The modern highly efficient units come, being a stainless steel
condensing boiler with an inbuilt heat exchanger that operates in order to
serve the customers with hot water immediately.
There are two main
reasons behind the combi boilers great and powerful efficiency i.e. these units
have high operating efficiency and low internal water volume. This means when
in summer days you don’t need space heating you are only paying to heat water
which is domestically required.
As the name says
‘Combi’, these boilers combine the functions of a conventional boiler, hot
water cylinder and a cold water storage tank. The Combi boilers have come being
really popular systems that are compact in size and are easy to install.
Combi boilers are
designed to be manufactured with two independent heat exchangers, one of which
carries a pipe to the radiators while the other one carries a pipe to the hot
water supply. As soon as you turn the hot tap on, your boiler fires up to heat
water and a valve gets opened to let the water flow through the network of
A combi boiler will
usually require to pause from heating the central heating water for your
radiators while it’s heating the hot water for your tap, because they are often
not build to supply enough heat to both the points at the same time. For this
reason, you might hear your boiler switching on and off when you run a hot
water tap even if they’re already lit to power the central heating.
Now that you know about
how a combi boiler works, you might me wondering about how to turn off hot
water supply combi boiler.
How to turn off hot water supply combi boiler?
Because of the water
being supplied directly in case of a combi boiler, closing the main stop valve
would shut the water off for you.
However, if your boiler
operates with a hot water cylinder, this means that the water supplies are
being fed indirectly and you, other than the main stop valve, need to turn off
the valve on the cylinder or cisterns outlet supply and you would be done with
