Install Boiler questions, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

It costs homeowners between $5,000 and $12,500 to install a new HVAC system. This number varies, as each home has its own heating and cooling needs. Even a home with the same footage and number of occupants will have different HVAC requirements based on the number of windows, the climate, and how often the occupants use the system. 

Both hydronic and electric hydronic heaters usually come with a higher price tag up front, but you can save more on energy costs over time compared to standard heaters. They also provide heat for a short time after the heater is actually turned off, making them more efficient. Additionally, standard convection heaters use electric coils to heat up the air, whereas hydronic heaters warm up water or oil which then heats the air.
