Renovations in single-family homes and flats
Heating Renovation: How you can Boost Efficiency
Renovation projects are one of the biggest opportunities for heating installers. Ageing properties, outdated heating controls, and inefficient hydraulic systems create ideal conditions for upgrades that improve comfort, reduce energy costs and extend the lifetime of heating systems.
With the complete IMI Climate Control product portfolio, installers can offer customers a reliable, future-proof heating renovation – covering room thermostats, radiator thermostatic heads, hydronic balancing, pressure maintenance and water quality.
Key aspects to consider before renovating
Upgrade Comfort and Control with Modern Room Thermostats
Many homes still use outdated or non-programmable controls. Replacing these with modern room thermostats significantly increases comfort and energy efficiency.
IMI room thermostats are designed for fast installation, reliable operation and easy integration in traditional and modern heating systems.
Radiator Thermostats: A Small Upgrade With a Big Impact
Radiator thermostats are one of the most cost-effective renovation measures. Old or fixed radiator valves often lead to overheating, cold spots and unnecessary energy consumption. IMI thermostatic heads provide:
- Quick replacement during renovation works
- Proven durability and long-term stability
- Precise temperature control in every room
- Options for retrofit applications
Many homes still use outdated or non-programmable controls. Replacing these with modern room thermostats significantly increases comfort and energy efficiency.
For homes with ageing or incompatible radiator valves, IMI offers a complete range of valve bodies and adapters, making upgrades simple and reliable.
Hydronic Balancing: The Most Important Renovation Measure
In heating renovation, hydronic balancing is often the missing piece. Without proper balancing, even modern boilers and heat pumps cannot perform efficiently. Benefits of hydronic balancing during renovations:
- Eliminates cold radiators and uneven heat distribution
- Ensures correct flow rates for every radiator
- Reduces pump energy consumption
- Improves system efficiency by up to 20%
IMI solutions such as Eclipse automatic balancing valves, enable installers to achieve perfect balancing without complex calculations. Automatic flow limitation ensures precise performance, especially in older heating systems.
Pressure Maintenance: Protecting the System Long-Term
Many older homes suffer from pressure fluctuations, loss of water and malfunctioning expansion vessels. During renovation work, checking and upgrading pressure maintenance is essential. IMI pressure maintenance products provide:
- Stable system pressure for sealed heating systems
- Reduced risk of system shutdowns and air ingress
- Longer lifespan of pumps, boilers and heat exchangers
- Reliable operation even in challenging system layouts
Systems such as Statico support residential and light-commercial heating installations during renovation and modernisation.
Water Quality: The Foundation of an Efficient Heating System
Poor water quality is one of the main reasons for system failures in renovated heating installations. Sludge, air and magnetite can dramatically reduce efficiency and cause pump damage. IMI water quality solutions ensure long-term system health:
- Zeparo air and dirt separators remove air, microbubbles and sludge
- Magnetite separation protects pumps and heat exchangers
- Improved heat transfer and reduced wear
- Ideal for older systems that accumulate deposits over time
In renovation projects, adding a Zeparo separator is one of the most effective steps to bring an old system back to high performance.
Current subsidy programmes
The Boiler Upgrade Scheme (BUS) offers homeowners in England and Wales grants of up to £7,500 if they replace an existing fossil fuel heating system with a new, low-emission heating system such as a heat pump or biomass boiler.
