Selecting a heated towel rail: aesthetic quality and functionality

In REJ Design products, beautiful industrial design and practicality go hand in hand. The timeless drying rack models are ideal for different spaces and purposes of use. All water heated REJ Design drying radiators are suitable for installation in domestic hot water supply and heating systems. We also have a broad range of electric drying racks. Drying radiators can be installed in new and renovated buildings, in bathrooms, toilets, utility and laundry rooms and vestibules. If the installation is to be as unobtrusive as possible, select the model which is best-suited for your purposes, choose its location, and make the required preparations at the planning, design and construction stages. A towel dryer is primarily intended for warming and drying towels and other textiles and for removing excess moisture from the room. It cannot stand alone as a heat source in larger rooms/spaces, but it gives additional warmth and comfort and helps to keep structures dry. Building supervisors recommend that a heated drying rack is used in wet rooms because it is an excellent addition to, for example, a floor heating system and helps to prevent any water and mould damage.


Water heated or electric?

When making your selection, first consider whether you want a water heated drying rack or an electric drying rack. A towel rail connected to the domestic hot water supply system is always warm (also in summer), while a drying rack connected to the water heating system is only warm during the heating season. In most buildings, the heating system is turned off in summer. The heating and drying capacity of a water heated drying rack is based on the temperature of the water circulating in the domestic hot water supply or heating system: the use of the towel rail generates no extra cost. According to Finnish building regulations, it is not permitted to adjust or stop the flow of a towe dryer connected to the domestic water supply system. When connected to the heating system, the drying radiator can be adjusted by using a separate regulator connected to the input tube. We recommend that all water heated towel warmers are installed by an HVAC professional.

In new buildings, water couplings for towel dryers are easy to arrange if they are taken into account during the design, planning and construction stages. A drying radiator can also be surface-mounted afterwards in most rooms where you have access to domestic hot water suppply or water heating system. Under specific conditions, a drying rack can also be installed in place of an existing flat panel radiator. A drying rack can also be connected to a water-circulating floor heating system. However, it should be noted that the temperature of the heated towel rail depends on the temperature of the water circulating in the system.


Installation of a water heated towel warmer during water line renovations in apartment buildings

It is very common in Finland that drying radiators are installed in bathrooms or toilets during water line renovations in apartment buildings. In addition to its standard model range, REJ Design manufactures water heated drying radiators customised, for example, for different connection distances. During modern bathroom renovations, the ceiling is often lowered so that water pipes can easily be led in to the room inside the ceiling. At such sites, water pipes are led from the ceiling to the top of the drying rack on the wall surface, resulting in an installation that is as unobtrusive and finished as possible. For such an installation, our model range also includes towel warmers with a top connection. These include a standard connection from the top feet (e.g. Tango products with a top connection, such as Tango BTH 35744 top, Tango BTH 35130 top, Tango BTH 50744 top, Tango BTH 50130 top, BTH 60744 top, etc.; see “Water heated towel rails” under products). We also manufacture to order other hot water operated drying racks with top, bottom or side connections, as well as drying racks connected from the ends of the vertical bars.


Electric towel warmers are easy to install

Electric drying racks are always delivered with a plug connection. The towel rails are easy to mount on the wall and connected to the nearest socket with the plug. The length of the standard power cord is 1.3 m. The protection class of electric drying racks is IP44 (resistant to splashing water), and they do not require any separate earthing because of their double-insulated design. Safe distances and building regulations should be taken into account with regard to the placement and installation of the towel dryer. At the design, planning and construction stages at new and renovated sites, preparations can easily be made for drying racks so that an authorised electric contractor can transform the towel dryer connection into a fixture or flush-mounting (the power cord will be hidden). We recommend that the position of the power cord and the diameter of the lead-through are considered already at the design/plannig/construction stage. Professionals can easily use a 16 mm electrical installation tube behind the selected mounting foot according to the handedness of the drying rack, and to lead the device cord to the connection box. If the connection box is far away, the drying rack can also be delivered with a 4 m cord upon request. If the location of the towel dryeer is taken into account early during the design and planning stage, the result will be finished and stylish.

Electric REJ Design towel rails have low power consumption: only 35–75 W, depending on the model. The approximate annual operating costs of a medium-sized drying rack are EUR 40–50 when the product is on 24/7 throughout the year. The towel rail also comes with an on/off switch, and it can be switched off, for example, during holidays. It is recommended that the drying rack is constantly on in wet rooms. This dries humidity from the air and helps to prevent water and mould damage.


A heated drying rack is ideal for every home

The selection of the drying rack model is affected, above all, by the available space and the needs of users. When selecting the model, consider the following:

– Where will the drying rack be installed? How wide and tall a space is available? What towel rail model has the best dimensions and design for the space/decor?

– How much can the towel rail extend from the wall surface if it is installed above a top-load washing machine, above or next to a toilet, or if it is installed close to a door that opens towards it?

– Is heating power a significant factor? Does the room have any other heating source? Does the room have an external wall or is it located in the middle of your apartment? Is there a window in the room?

– Who will use it? How many people will use the drying radiator(s)? Do you need one or more drying racks?

– For what purpose will the drying rack be used?

– What will you be drying? Will the drying rack only be used for drying/warming towels, for laundry, or will you also be drying outdoor clothes, hand-washed items, cleaning cloths and other such items?


Surface treatment and colour options for towel rails

The standard finishes of towel rails are chrome and white (RAL 9010 semi-gloss). Other surface treatment options are available upon request.

As the chrome surface stores heat, it is ideal for drying textiles. Then again, a painted surface lets heat penetrate it, and it heats the room more effectively. Chrome is a timeless and stylish choice, especially when the taps and other water fixtures are chrome-plated. The tone of the drying rack can also match its background, and it can be treated in the same colour as the wall tiles, etc. Matte black and other dark tones are popular in hallways. Paint tones in orders must be selected from the RAL colour chart (available, for example, from hardware stores). Please verify the availability of special colours before placing your order. For printing reasons, the tones shown in the colour chart do not fully represent the actual drying rack tones, and the drying rack tone is usually a little darker. When selecting the colour, note that the product has a long life, and it may be used for more than 20 years starting from the installation date.
