Can you have 2 thermostats on one boiler?

4 Answers. As long as the boiler is capable of providing enough hot water through the system to heat the whole house if necessary you shouldn’t have a problem. What you are proposing is a “coarser” version of thermostatic valves on each radiator and that is perfectly safe for a combination boiler.

Can a steam boiler be zoned?

The water in a steam boiler is too dirty to be flowing through the tight confines of the plastic or synthetic rubber tubing we use in radiant systems. If you want radiant, the pro can still add a zone off of your steam boiler, but he’ll have to use a heat exchanger and a second circulator.

Can you use a steam boiler as a hot water boiler?

Both steam boilers and hot water boilers offer energy efficiency, but in different ways. A steam boiler uses more energy to boil the water, but uses less energy during the transfer of heat. A hot water boiler uses less energy to create hot water, but more energy during the transfer of heat.

How many zones does a house have?

The ideal number of zones to be installed in one house is 2. This is being divided and categorized as upstairs and downstairs. But each HVAC system can be set up to accommodate multiple zones. Each room can even function as its own zone.

How does Nest work with two thermostats?

Nest thermostats in the same home don’t share temperature schedules. Each Nest thermostat learns a separate schedule for the zone that it controls. So you can teach your thermostat downstairs to warm up the kitchen in time for breakfast, while the thermostat upstairs turns down for the day.

Do you need two Nest thermostats for 2 zones?

As you asked the question, each thermostat is individually controlled, so yes, you will need to have two Nest thermostats if you want the benefits of Nest in both areas.

How do you run a hot water zone off a steam boiler?

Pipe in two ball valves (or gate valves) and two boiler drains below the boiler water line. Shut both ball valves (or gate valves). Now connect the garden hose to one of the boiler drains and let the other flow freely to a drain. Fill the zone piping under city water pressure until all the air comes out.

How does Zone 2 work in a boiler?

Zoning is achieved by using a solenoid valve for each zone – 2 in your case after the pump. You only use one pump. The Thermostats – 2 in your case control the solenoid valve. So when your downstairs thermostat calls for heat it opens the Solenoid valve, the pump starts and your boiler goes into action.

What should the water level be in a steam boiler?

Usually a half copper water line is connected to the steam boiler. Water can be added slowly when the boiler is not hot. Generally water in the sight glass should be half to two-thirds full. If the level of water is higher than this, some water may need to be drained out until it reaches this level.

Is there a limit to how much radiation a steam boiler can support?

Yes, but there is a limit to how much radiation your steam boiler can support. Manufacturers list two capacity outputs on every steam boiler: the Department of Energy (DOE) capacity, aka the boiler’s gross output, and the boiler’s net capacity.

Is the baseboard hot water zone off steam?

The original parts of the house use steam-heated convectors to supply heat. Two additions, a large bedroom and a large kitchen, are heated by baseboard hot water off the same boiler.
