WHAT SHOWER CAN I FIT?
When deciding on the best shower for your home you’ll be presented with a lot of choice. Factors to consider include shower type (smart digital, electric, mixer, power), the number of shower heads/outlets and their style, round vs. square valves and in wall (concealed) vs. on wall valves (exposed).
However, the most important consideration that will affect the performance is the water system that supplies your shower. That’s why we’ve put this handy summary together to help you understand the differences, as these will affect the type of shower that you could or should be installing.
There are three main water systems; gravity, combination boiler and unvented mains-fed (High pressure or HP system).
WHAT IS A GRAVITY SYSTEM?
Gravity water systems are the traditional plumbing system in the UK and tend to be found in older properties.
They have a hot and cold water feed consisting of a cold water tank, usually located in the roof space, and a hot water cylinder, frequently in the airing cupboard.
The greater the distance from the bottom of the cold tank to the top of the shower head, the better the shower’s performance. A booster pump is often added to the water system to increase the flow rate performance of the shower.
Large tank capacity
Stored hot water, ready to use
Ability to add a pump for increased shower pressure
Capacity of tank can be a limitation for large families and shared dwellings
Time to reheat water can be lengthy
WHAT IS A COMBINATION BOILER SYSTEM?Cold mains water feeds the shower and supplies the combi boiler. Combi boiler systems heat your water as you use it and consist of a boiler attached to a wall, often in the kitchen.
This water system isn't suitable for use with booster pumps.
Only pay to heat the water you use
Never run out of hot water
No stored supply of hot water if boiler were to breakdown
WHAT IS AN UNVENTED MAINS-FED SYSTEM?
Cold mains water feeds both the shower and hot water cylinder directly. The hot water cylinder is usually located in the airing cupboard, utility area or garage, with many being recognised by the expansion vessel on the top. These systems are usually found in newer or refurbished properties.
This water system isn't suitable for use with booster pump.
Mains pressure hot water
Stored hot water, ready to use
No need for a cold water storage tank
Capacity of tank can be a limitation for large families/shared dwellings
DO YOU WANT TO USE YOUR EXISTING HOT WATER SYSTEM?
It’s important to ask yourself whether there will be enough hot water to service the demand placed on your new shower by everyone that will use it, as well as the rest of the property, because this will influence the type of shower you choose. If you are unsure whether you have enough hot water, contact your plumber.
