Frequently Asked Questions – Heaters & Stoves for Hot Tubs (UK)
🔥 What is the best heater or stove for a hot tub in the UK?
The best heater depends on your hot tub size, available space and how quickly you want the water to heat. For most UK gardens, wood-fired stoves are the most popular choice thanks to their low running costs, strong heat output and eco-friendly fuel. Integrated and submersible heaters are ideal for compact tubs, while external heaters suit larger garden installations.
🪵 How long does a wood-fired hot tub heater take to heat the water?
On average, a wood-fired hot tub stove heats the water in 2–3 hours from cold to bathing temperature (38–40°C). Heating time depends on:
- Outside air temperature
- Stove type (internal, external or submersible)
- Water volume
- Type of wood used
Smaller tubs with integrated or snorkel heaters usually heat faster.
🔧 What is the difference between internal and external hot tub heaters?
- Internal / submersible heaters sit inside the tub water and heat it directly. They are compact and highly efficient.
- External heaters are positioned outside the tub, connected with pipework. They free up bathing space and are often easier to maintain.
Both options provide excellent performance — the best choice depends on your space and layout.
🌿 Are wood-fired hot tub stoves eco-friendly?
Yes. Wood-fired heaters are one of the most environmentally friendly ways to heat a hot tub, especially when using sustainably sourced firewood. They produce minimal emissions compared to electric heating and do not rely on the power grid — ideal for off-grid gardens and rural UK locations.
💧 Can I use a hot tub stove for pools as well?
Yes. Some models, such as wood log-fired stoves for pools and hot tubs, are designed to handle larger water volumes and can be used for:
- Hot tubs
- Cold plunge pools
- Swimming pools (small to medium size)
Always check the recommended water capacity of the stove before installation.
🛠️ Do hot tub heaters require professional installation?
Most external and submersible heaters can be installed by a competent DIY user with basic plumbing knowledge. However, for integrated stoves or permanent garden setups, we recommend professional installation to ensure correct water flow, safety clearances and chimney draft.
🔒 Are wood-fired hot tub stoves safe to use?
Yes, when used correctly. All our hot tub stoves are designed with:
- Heat-resistant steel construction
- Controlled water circulation
- Secure flue connections
- Safe firebox access
Always follow the supplied installation guide and never operate the stove without water in the system.
📏 How do I choose the right size heater for my hot tub?
To choose the correct heater size, consider:
- Tub diameter and water volume
- Number of bathers
- Desired heating time
- Whether the tub is insulated
Larger tubs (6–10 persons) benefit from external or high-power log-fired stoves, while 2–4 person tubs work perfectly with submersible or integrated heaters.
🚚 Do you deliver hot tub stoves across the UK?
Yes — we offer reliable UK-wide delivery for all hot tub heaters and stoves. Your order will be safely packed and shipped directly to your address with tracking provided.
Wood Fired Heater for Hot Tubs

Albert and his team at TimberIN were professional and helpful all the way through, and the tub was delivered exactly as planned. It looks great and works very well. I opted for an electric water heating system and this works well, but we have not yet resolved how to control the temperature automatically.
We are over the moon with our new tub. It was delivered by the nicest delivery guys, it was easy to assemble and within a few hours it was hot enough to use. Already in just over 24 hours the kids have had great fun and the adults have enjoyed sitting under the stars. Another amazing attribute to these high quality tubs is that you can literally put them anywhere. Even the smell of burning wood wafting over adds to the overall experience. The price is amazing and we will no doubt be buying another for our holiday cottage business very soon. Thank you.
Thanks Albert and please make sure you praise your delivery guys too they represent your company perfectly. So efficient and polite.
Hi Albert Hot tub installed and already used by family and friends. Good experience dealing with yourselves and would highly recommend your company All the best Gary
