Will a combi boiler increase hot water pressure?
Will a combi boiler increase hot water pressure?
Unlike conventional boiler systems, it is not possible to install a boiler pump to increase water pressure because a combi boiler must take water directly from the mains. If your home is in an area with a low flow rate, the combi boiler will always be limited in the strength of water it can send to taps and showers.
How does a combi boiler work in a shower?
These models connect to both your hot and cold water supply and deliver water at the temperature you want. Because they require hot water fed by your boiler – and a combi appliance has limited capacity – they may not deliver water at the pressure you want, particularly if other showers or taps are in use.
Can a combi boiler be used for central heating?
The KW heat output must be checked and be sufficient for your premises prior to installation, remember that combi boilers have a heat output for Domestic Hot Water and a heat output for Central Heating. A common mistake is to size the boiler just on the central heating KW demand.
What does the flow rate of a combi boiler mean?
The flow rate simply refers to how much water can pass through the appliance to feed taps and showers once the boiler is working. Choosing a powerful combi boiler with a good flow rate will help you to optimise hot water pressure around your home.
Why does my combi boiler have no hot water?
With the likely culprit being the aforementioned leakage, under or over pressurisation could result in no hot water from your combi boiler. If your boiler is low on pressure, it can usually be solved simply through a DIY top up.
Can a combi be used as a water heater?
There is a way it can be done but it must involve creating a small loop between the flow an return on the boiler and then charging that loop up. The boiler will then be able to heat the exchanger to heat the water. Note I have never done this before but have known of people temp running a combi as a water heater.

Is the combi boiler used in the UK?
Most UK homes rely on a gas combi boiler for both heating and hot water. As well as being effective and economical, they also have a reputation for being extremely reliable. However, as a piece of equipment that is typically in use 24 hours a day seven days a week, it is inevitable that from time to time problems may occur.
