What Size Tubular Heater Do I Need

I know that during these cold winter months you’re all looking to save money on your heating bills. Tubular heaters are a great way to do just that, but they come in many different sizes and it can be hard to figure out which size you need.

I’ll go through the basics of choosing the right size for your home so you can start saving money today!

What Size Tubular Heater Do I Need?

If you’re looking for a tubular heater to heat up your home, you may be wondering what size tubular heater do I need?

The answer is not as simple as it seems. There are many factors that go into determining the correct size of your heating system and we’ll explore them in this blog post.

First, let’s talk about how much space you want to cover with the heat given off by the heater. The larger area, then typically the more BTUs (British Thermal Units) will be required to sufficiently warm-up that area. For example, if someone has a 400 square foot room they would like to keep at 70 degrees Fahrenheit all day long they could use an 800-1000 BTU unit while someone with a much larger area to heat, such as a 2000 square foot basement could need a much larger heater.

It is also important to consider special factors that affect the heating situation. The location of your home can determine how well a space heater will work for you. For example, a house in Minnesota or Maine might require a much stronger unit than an apartment in Florida or California.

The width and length of your heater also matter, the longer the tube element within your unit means more BTUs are required to heat up an equivalent size room. Also, there are sub-types of tubular designs out there; some draw air from outside of the home while others act like furnace systems with hot air being circulated by fans through ductwork throughout various rooms.

It is important to consider all of these factors when purchasing a tubular heater and to do the math yourself in order to make sure you’re getting the best heating unit for your needs and budget.

What is a tubular heater?

A tubular heater is a type of heating system that uses electricity to heat an element (tubing) which in turn heats up the surrounding air. These systems are often wall-mounted and may resemble radiator units, but they do not use hot water like radiators; instead, they act as convective heaters with the heated element passing along heat to the surrounding room. The benefit of sub-type designs that work like furnaces with ductwork is that you can push conditioned hot air throughout your home or office rather than just heating up one single space.

How much does a tubular heater cost in the UK?

The initial cost for many tubular electric heating systems is relatively low when compared to other types of home heating solutions such as forced-air gas furnaces or hydronic heating systems. It is important, however, to consider long-term operating costs for these products as well as the cost of installation and maintenance.

Generally speaking, it’s best to favour a heater with a “lower” wattage rather than one with a high wattage if you’re looking for a more efficient unit. For example, an 800 Watt heater might be all that is needed to heat up an area roughly 20 feet by 30 feet while a 1000 Watt unit would over-work itself trying to do the same job – resulting in wasted energy and increased heating bills.

In short: Heaters with lower wattages will typically last longer and use less energy over time.

Where can I buy a tubular heater?

Tubular heaters are readily available for purchase from many large department stores and hardware/DIY chains such as B&Q, Homebase, Wickes, Screwfix and others. Online retailers including Amazon.com offer a wide selection of electric space heaters to choose from at a relatively low cost compared to other forms of heating systems – but again, do the research on wattage requirements prior to making a final choice.

How much does it cost to run a tubular heater?

Pinpointing an exact number for how much it costs will vary depending on your home’s utility provider and also where you live in the country. In some areas, electricity rates may fluctuate during peak hours so running your heater during off-peak hours could result in significant savings.

Make sure to check with your utility for more information on how much it costs to run a tubular heater and which times of the day are billed at lower rates.

What temperature do tubular heaters reach?

Tubular heaters are capable of quickly warming up areas within the home however, many do not have thermostats to control their level of output. Instead, you must manually turn these units on or off in order to achieve whatever temperature you prefer – which may be a potential safety concern for those with children and pets as one cannot completely avoid contact with heated surfaces.

Consult your tubular heater’s manual regarding maximum operating temperatures as this will vary between models as well as manufacturers so take note.

How much electricity does a tubular heater use?

Electric heaters of all types can be responsible for a significant increase in your monthly utility bills. In order to determine how much an individual unit costs to run, divide the heater’s wattage by 1000 and then multiply that number by your average cost per kWh as this will give you a rough estimate of how much it costs per hour to run the product. For example, if you have a 1000 Watt tubular heater with an average rate of £0.12/kWh:

1000 divided by 1000 = 1

1 x 0.12 = 0.12 or 12 pence per hour

Multiply this result by 24 hours and 365 days (or 8,760 hours) and you will get your approximate annual cost – which would work out to roughly £115 annually.

Talking about the price, tubular electric heaters often carry a relatively low initial cost but you must be aware of the running costs as well as installation and maintenance expenses – which can set you back more than you expect!

How does a tubular heater work?

Tubular heaters (simply referred to as “tubular”) are cheap and effective forms of home heating that use convection currents to push warmth through conduit ductwork is that you can push conditioned hot air throughout your home or office rather than just heating up one single space.

The initial cost for many tubular electric heating systems is relatively low when compared to other types of home heating solutions such as forced-air gas furnaces and wood stoves – but you must be aware that these units require the installation of ductwork in order to function properly. This can add into the overall cost quite a bit so it’s important to take this into consideration when making a final purchase decision.

When compared to other heating systems:

Other types of electric heaters such as room heaters, oil-filled radiators or ceramic disc elements often offer far superior levels of comfort when used – especially when placed next to one another within the same space. Tubulars are not known for their ability to warm up large areas (or rooms) effectively unless there is more than one unit installed at different locations throughout the structure.

Space heaters too can provide comfortable warmth in one single area while some electric models can be programmed to turn off automatically when they detect no one is present in the room – making it an effective solution for homes or businesses where children or pets are often present.

Are tubular heaters safe?

The use of ductwork on tubular heating systems means that these products offer up some additional safety benefits when compared to other types of home heating solutions however, there are still many risks to take into consideration before you install any heater (such as a tubular) within your home.

For example, anyone buying a heater should always read the instructions and manufacturer’s manuals carefully before installation begins – especially with regards to clearance distances which must remain free at times along with proper ventilation. Having a qualified electrician install your unit within the close proximity of flammable materials such as curtains or other household items can be dangerous – so it’s very important to consult manufacturer installation guidelines before you begin.

Residents in rented properties should always check with their landlords or real estate agents prior to installing any electrical heating solutions in order to avoid complex legal issues down the line. If in doubt, call an electrician!

Are there alternatives?

Tubular heaters are generally cheap and effective but when compared with other forms of electrical home heating they are far from perfect when used on their own. A combination of smaller sized space heaters working together can often achieve even more energy savings than a tubular unit so if possible, try to combine these types of products together for the best results.

Having said that, if you do choose to use a tubular electric heater as your primary heating solution it is very important to make sure you like the way it looks and functions within the designated space – especially if you plan on spending a significant amount of time (or money) buying and installing this type of heating system. Never compromise on what’s most important – comfort!


Tubular electric heaters can be a great choice if you’re looking for an inexpensive way to warm up an area that doesn’t require large amounts of heating power. Look for other eco-friendly options such as radiant floor heating systems as a starting point to help determine your home’s heating requirements and compare them against other types (and wattages) of space heaters available online or from local retailers.
