Frequently Asked Questions

Is my home suitable for a heat pump?

Our free survey includes a detailed heat loss analysis of your home, ensuring your insulation renders your home suitable for a heat pump installation. This will let you know whether changes are required. We can provide you the necessary solutions if that’s the case, if you are willing to proceed.

Will my energy bills go up?

Whether your bills increase depends on several factors, including the correct installation of a properly sized system. Many installers fail to match the right heat pump to a home’s specific needs. At Cosy Castle, we conduct a thorough heat loss analysis and tailor the system to your home, ensuring maximum efficiency. Our expert team also guides you on proper usage and monitors your system to help you optimize savings. All our clients have seen reductions in their energy bills thanks to these measures.

Do I need bigger radiators?

With our careful sizing process, we ensure that the correct system is installed to meet your specific needs, eliminating unnecessary costs or inefficiencies.

What makes your air to water heat pump system different?

Our ASHP systems are equipped with inverters to optimize energy usage. With the 3i Box, you can remotely monitor and adjust your system for peak efficiency.

How does Cosy Castle help with government grants?

Cosy Castle handles the entire paperwork process for government grants and applies on your behalf, ensuring that you receive the maximum financial aid available for heat pump installations. You only pay the final price with the grant already factored in.

How long does installation take?

The installation typically takes 1-2 days, depending on the complexity of your system. Our expert team ensures minimal disruption to your home.
