Depend on Central Cooling & Heating to recommend the best combination unit for your needs.
A combination unit is a high-efficiency water heater and a central heating boiler combined within one compact unit. Water is heated directly from the water main eliminating the need for a hot water storage tank. Because hot water is delivered to your taps or showers at high pressure, it’s very convenient and can save on your hot water costs.

Our expert technicians will help you understand more about your options. We offer affordable prices, repair, installation and maintenance services on Bosch and many other brands.
