What Is A Tankless Water Heater?
Tankless water heaters, also known as on-demand or instant water heaters, provide hot water exactly when you need it, without storing it in a tank. When you turn on a tap, cold water travels through the unit and is heated immediately.
This setup has made them increasingly popular across Brixton, particularly in smaller homes or flats where saving space and energy are top priorities.
Pros Of Tankless Water Heaters For Brixton Homes
1. Instant, On-Demand Hot Water
No more waiting for a tank to refill. With on-demand hot water, you get a continuous flow—ideal for busy homes with multiple users or back-to-back baths.
2. Improved Energy Efficiency
Since water is only heated when needed, tankless systems avoid the standby energy loss of traditional cylinders. This increased energy efficiency can reduce energy bills significantly over time.
It’s a smart choice for Brixton residents looking to reduce their carbon footprint and energy consumption.
3. Saves Space In Compact Homes
Flats and terraced houses in Brixton often lack storage space. Tankless units are compact and can be installed on walls, in cupboards, or even outside, freeing up valuable space that would otherwise be occupied by a storage tank.
4. Longer Lifespan
With regular maintenance, a tankless water heater can last 15 to 20 years, compared to 10 to 12 years for conventional systems. Their durable design makes them a solid long-term investment.
5. Reduced Iron Oxide Risk
Unlike traditional water tanks, tankless systems don’t store water long-term, reducing the risk of iron oxide buildup. This helps protect your heating system and reduces the likelihood of blockages in your plumbing.
Cons Of Tankless Water Heaters For Brixton Homes
1. Higher Initial Cost
Upfront, these systems can be more expensive to install, especially if pipework or gas lines need upgrading. However, long-term savings often offset the initial cost.
2. May Struggle With Simultaneous Demand
If you run a bath and the washing-up tap at the same time, a single unit may not be sufficient. Larger households may need more powerful systems or dual units to ensure consistent on-demand hot water.
3. Installation Challenges In Older Homes
Some older Brixton homes may require additional modifications to accommodate tankless systems. These can include upgrades to gas pipework or the addition of a pressure-reducing valve to manage mains pressure.
4. Regular Maintenance Is Still Needed
Although these units are more efficient, they still need annual maintenance to keep them running well. We recommend yearly checks to clean filters and inspect heating elements.

Other Important Considerations Before Installation
1. Water Pressure In Your Area
Brixton homes typically receive water at around 1–3 bars, which is ideal for tankless systems. However, if your property has pressure issues, we may recommend installing a pressure-reducing valve to balance flow and prevent system strain.
2. Building Regulations & Compatibility
In older properties, your plumbing or ventilation may need updating to comply with UK regulations. Our experienced engineers ensure every installation is safe, compliant, and efficient.
