Can boiler explode?

Yes, in rare cases a boiler can explode, but modern boilers are designed with multiple safety features to prevent this from happening.

An explosion is usually the result of:
✅ Severe neglect (no servicing for years)
✅ Faulty pressure relief valves
✅ Gas leaks combined with ignition
✅ Serious internal corrosion or damage

👉 Regular servicing and keeping your boiler in good repair makes the risk extremely low.

What boiler do I need?

What boiler you need depends on your home and your needs. Here’s a quick guide to help:

🏠 1. Combi Boiler (Combination Boiler)

✅ Best for small to medium homes with 1-2 bathrooms
✅ No separate water tank needed
✅ Heats water on demand — good for hot taps and showers
✅ Space-saving and energy-efficient

🏠 2. System Boiler

✅ Best for medium to large homes with more than 1 bathroom
✅ Uses a hot water cylinder (tank)
✅ Great if you want strong water pressure for multiple taps/showers running at once

🏠 3. Regular / Conventional Boiler

✅ Best for larger homes with old radiator systems or where you already have a hot water tank
✅ Works with a separate hot water cylinder and cold water tank
✅ Ideal if you need lots of hot water or already have a traditional system

Choosing the right boiler depends on:

• The size of your home

• Number of bathrooms

• How much hot water you use

• Your current system (new install or replacement)

Boiler Service?

explanation of a boiler service:

👉 A boiler service is a professional check and clean of your boiler, done by a qualified engineer — usually once a year. The frequency may be increased on usage. It helps keep your boiler:
✅ Safe
✅ Efficient
✅ Reliable
✅ In line with warranty and legal requirements (if you’re a landlord)

What’s included in a typical boiler service:

🔍 Visual check — looking for leaks, corrosion, damage
🧼 Cleaning — key components (like heat exchanger & burner)
📋 Safety checks — flue, gas pressure, seals
📈 Performance test — making sure the boiler is running correctly
🗂️ Service record — you’ll receive a report and certificate

Why it matters:

✅ Helps avoid breakdowns
✅ Can lower your energy bills (an efficient boiler uses less gas)
✅ Catches small problems early before they become expensive
✅ Required annually to maintain many boiler warranties
✅ If you’re a landlord — legally required as part of your Gas Safety responsibilities

Typical cost: £70–£120 depending on boiler type and location.
Time needed: About 20–60 minutes.
