Polar Heating
Unvented Hot Water Cylinders in Wimborne and Poole
Unvented hot water cylinder enquiries for homes needing help with hot water pressure, cylinder faults, valves and servicing questions.
How we can help
Unvented hot water cylinders can provide strong mains-pressure hot water, but they need the right knowledge and careful handling. If you have poor hot water pressure, discharge pipe dripping, no hot water from the cylinder or concerns about valves and controls, it is worth getting proper advice.
Polar Heating takes unvented hot water cylinder enquiries across Wimborne, Poole and nearby areas. We can discuss the symptoms, the cylinder make and model and whether the issue appears to be plumbing, controls or heating related.
Because unvented cylinders are safety-critical appliances, only suitable qualified work should be carried out. The advice will be based on the cylinder, installation and the current scope of work required.
Tell us what has changed, whether the tundish or discharge pipe is running, and whether you have heating, hot water or both affected.
Useful tips before you call
- Do not cap, block or ignore a running discharge pipe or tundish.
- Make a note of the cylinder make, model and approximate age.
- Explain whether the issue affects hot water only or heating as well.
- Send photos of the cylinder label and pipework if it is safe.
- Mention any recent plumbing or boiler work.
Send the cylinder make and model, photos if safe, and describe whether the issue affects pressure, heat or discharge pipework.

Common questions
Can you help with unvented hot water cylinder problems?
Polar Heating can take unvented hot water cylinder enquiries in Wimborne, Poole and nearby areas and advise on the next step.
What is a tundish?
It is part of the discharge arrangement on many unvented cylinder installations. If water is visibly discharging, the cause should be checked rather than ignored.
Can an unvented cylinder affect hot water pressure?
Yes, cylinder, valve, pressure and supply issues can affect hot water performance. A proper check is needed to identify the cause.
Is this different from a boiler repair?
Yes. Cylinder issues can be separate from boiler faults, though the heating system and controls may still be connected.
