Can you use a tankless water heater for baseboard heat?
Though they are sold primarily for domestic hot water, tankless heaters are actually well-suited for radiant heating, which operates at low temperatures compared with, for example, hot-water baseboard. So using the unit for radiant heating generally has little or no effect on the sizing calculation.
How does a hot water zone valve work?
Each zone valve is controlled by its own zone thermostat. End switches in each zone valve control the central circulator and the burner. On a call for heat, the valve is opened. This ensures that the circulator and burner are powered when any zone calls for heat.
How does a baseboard hot water heater work?
I have baseboard hot water heat. In one of my heating zones, there are three “loops”. (i.e. shortly after the supply leaves the zone valve, the pipes split in three directions. These pipes then eventually join back together and return to the boiler.) One of the three loops supplies just a single radiator in our mudroom.
How does a zone valve work on a hot water heater?
Zone Valves on Indirect-Fired Domestic Hot Water Heaters. A separate loop of piping conducts water from a nearby heating boiler, through the coil in the bottom of the indirect fired water heater tank (thus transferring heat to water in the water heater tank), and back to the heating boiler.
How many zones does my hot water system have?
I have a hot water heating system that presently has 4 zones:1st floor,2nd floor and 2 radiant heat zones. The plumber has installed the new circulator and the thermostat is in place. Neither the plumber or electrician seem to know how to wire it all to the boiler. I’m a retired building engineer and would like to take it on.
Which is better for controlling multiple heating zones?
Approaches to multiple heating zone control for hydronic (hot water) heating systems: Heating zone circulator pumps versus heating zone valves: which approach is better for controlling multiple heating zones in buildings? This article series describes how to diagnose & fix circulator pump problems on hot water or hydronic heating systems.
I have baseboard hot water heat. In one of my heating zones, there are three “loops”. (i.e. shortly after the supply leaves the zone valve, the pipes split in three directions.

How to create zones in a hot water heating system?
6 Solder together new zone valve assemblies and attach to boiler with solder-less fittings. 7 Install wireless thermostat in room of new zone; locate thermostat away from direct sunlight or cold drafts, and about 60 inches above the floor.
How does a zone valve on a heating system work?
at ZONE VALVE MANUALS & WIRING. In all cases, when the zone valve is fully open, an “end switch” inside the valve tells the heating system’s circulator to begin operating, causing hot water to flow through the zone.
How does the temperature of the baseboard affect the heat?
Heat output from baseboard depends largely on water temperature. The chart below shows how pronounced this effect is for a typical residential system. As water flows through a series piping circuit containing several baseboards, its temperature is constantly decreasing.
