To better control the flow of water to your hydronic towel warmer, consider using one or both of the valve types discussed below.

Isolating ValvesIsolating ValvesThe most basic valves you should add to your hydronic towel warmer are isolating valves. Isolating valves allow you to shut off the flow of water from your boiler to your towel warmer when maintenance is needed.

Without two isolating valves (one for each end of the towel warmer piping), any repair that’s necessary can become rather difficult. They also allow you to turn your towel warmer off when you’re not using it, saving some energy along the way.

Thermostatic Valves

Thermostatic ValvesBy default, your towel warmer will give off a standard amount of heat determined by the boiler. Thermostatic valves allow you to adjust the output of the towel warmer based on your comfort level. This is especially important if you hope to use the towel warmer as the main source of heat for your bathroom, too.

You'll only need one thermostatic valve per towel warmer, and since they can also shut off the flow of water, you can simply pair it with a single isolating valve for full water-flow control.

Hanging Accessories

Some hydronic towel warmer brands offer accessories for additional drying space or alternative hanging styles.

RingsTowel Warmer Knobs: Perfect for hand towels, rings can ensure your smaller linens don’t fall to the ground when you’re not looking.

Knobs: Use knobs for hanging larger items, such as robes or coats, or even just as accents for some added texture.

Drying Racks: Need more space than your towel warmer provides or your wall allows? Use an expanding drying rack to add additional hanging bars without having to expand vertically or horizontally.


Mounting and Dimensions

When choosing a size and mounting location, consider both the material of the wall and your access to piping. Mounting the unit into studs is recommended as some towel warmers can weigh up to 100 lbs, especially after adding heavy wet towels.

Space heating With Towel Warmers

Since towel warmers are effectively stylized radiators, you can choose to have your towel warmer also serve as an auxiliary heat source for your bathroom. It's a great option for bathrooms with poor heating and can be more energy efficient in place of turning up the thermostat every morning to heat every room in the house.

If you elect to go this route, make sure you size your towel warmer based on the BTU it can provide your space. To find out how many BTU/Hr you need to effectively heat your room, use our space-heating sizing tool below.
