A Heating Solution Tailored to Your Home
No two homes are exactly the same. A modern family home in Penzance will have different heating requirements to a period property in Pendeen or a converted chapel in rural Cornwall.
Our team takes the time to understand your property’s heating demands before recommending a suitable boiler and system design. We consider factors such as energy efficiency, property size, hot water usage, and your budget to ensure you receive a heating system that performs reliably for years to come.
Whether you are replacing an ageing boiler, upgrading to a more efficient model, or undertaking a larger renovation project, we can guide you through the options available.

What Our Customers Say
Much of our work comes through recommendations from existing customers, and we are proud of the many 5 Star Google reviews our customers leave.
Ray Crocker shared his experience following a recent installation:
“Jack, of Piran Plumbing, fitted a new boiler for us last week. We had suffered a leaky old boiler on and off for some time. Jack was prompt and efficient. He was also tidy and well organised, showing respect for our kitchen. We are grateful to have a new boiler with a 10 year guarantee, painlessly installed.”
Gas and Oil Boiler Installations
At Piran Plumbing, we install both gas and oil boilers from leading manufacturers, allowing us to recommend the best option for your home.
Modern boilers are significantly more energy efficient than older systems, helping reduce fuel consumption and potentially lowering heating costs. New installations can also provide more reliable heating, improved hot water performance, and quieter operation.
If your existing boiler is over ten years old, requires frequent repairs, or is becoming increasingly inefficient, upgrading to a modern system could be a worthwhile investment.
Our team will explain the available options clearly and provide honest advice without unnecessary pressure.
