How to Choose the Right Boiler for Your Home in Hertfordshire & North London
How to Choose the Right Boiler for Your Home in Hertfordshire & North London
Introduction
Choosing the right boiler for your home can feel overwhelming.
There are too many options, too much jargon — and plenty of conflicting advice.
If you’ve already replaced a boiler once before (and been let down), or if you’re upgrading an older property, you’ll know it’s not just about buying the cheapest unit or the one with the biggest brand.
It’s about getting a system that works perfectly for your home, your lifestyle, and your future plans.
In this guide, we’ll show you how to choose the right boiler — and how to avoid the common mistakes that leave many homeowners frustrated and out of pocket.
Why So Many Homeowners End Up With the Wrong Boiler
We hear this story all the time:
👉 “We had a new boiler fitted last year, but it still takes ages to run a bath.”
👉 “Our builder just told us to get a combi, but now it can’t cope with the kids all having showers.”
👉 “The plumber talked us into an expensive system that’s way over the top for our house.”
The problem?
Most boiler installs are done with little thought to:
The size of your home
How many bathrooms you use at once
Your water pressure
Future plans (extensions, loft conversions, bigger family)
What Homeowners Often Try (That Doesn’t Work)
👉 Buying a boiler based on brand alone
(“Everyone says Worcester is good, so we just got one”)
👉 Trusting an online “what size boiler do I need” calculator
(Most don’t take your actual hot water demand into account)
👉 Going with the cheapest installer they can find on Checkatrade
(Boiler works — but pressure and flow are poor. No real design done.)
👉 Letting a builder choose the boiler
(Builders are not heating engineers. We see this mistake constantly.)
The Dream Outcome You Actually Want
When you invest in a new boiler, here’s what most homeowners REALLY want:
✅ Hot water at all outlets — with good pressure
✅ Fast bath fill times
✅ Consistent temperature — no sudden cold spells in the shower
✅ A system that runs efficiently and quietly
✅ Reliability — no more unexpected breakdowns
✅ A solution that can handle future upgrades (more bathrooms, underfloor heating, etc.)
✅ A trusted installer who explains everything clearly and does the job properly
That’s exactly what we aim to deliver with every Sable Projects installation.
The Core Boiler Types Explained (Plain English)
Combi Boiler
Heats water on demand → no separate cylinder
Ideal for small to medium homes with 1–2 bathrooms
Space-saving, efficient — but may struggle with multiple bathrooms
System Boiler
Works with a hot water cylinder → stores hot water
Great for larger homes or where multiple bathrooms are used at once
Better flow rates and consistency
Conventional Boiler (Heat-Only)
For homes with older radiator systems or existing tanks
Rarely fitted in modern installs, but sometimes still suitable for heritage properties
“We install trusted brands like Vaillant and Worcester Bosch, depending on what’s best for your home.”
