Types of Hot Water Cylinders We Install and Repair

• 

  Vented (Traditional)

  Gravity-fed and basic, vented cylinders sit in a loft. They’re reliable, but they must be carefully cleaned to prevent leaks and pressure issues.

• 

  Unvented (Mains Pressure)

  Unvented cylinders that can be fitted with a 3kW (normal), 6kW, or 9kW immersion heater to supply mains-pressure hot water. Perfect for people with high hot water demands.

• 

  Direct/Indirect Heating Methods

  Direct cylinders transfer heat from a boiler directly to the water. Indirectly used a secondary or coil heat source. We’ll detail which setup works best for your home and lifestyle.

You've got questions? We've got answers!

How do I know if I need a new hot water cylinder or tank?

If you experience sudden exhaustion of hot water, low pressure, or tank leakage, it’s a sign. You should be able to count on your hot water cylinder (or tank) for reliable, consistent service, if it’s struggling, replacing it could be safer and cheaper.

Can you replace my tank in one visit?

Often, yes. After a site and system review, our G3-qualified engineers can remove the old cylinder, install the new one, and ensure everything is in working order with minimal disruption.

How much will a new hot water tank cost?

Prices vary by size and type. We offer a straightforward, fixed-price quote upfront so you know exactly what you’re getting. No hidden fees.

What’s the difference between Gas Safe and G3?

Gas Safe covers boilers; G3 qualification is specific to unvented hot water cylinders. Only G3-qualified engineers can legally install or service these systems safely.
