Boiler Buyer's Checklist

✅ Boiler Buyer’s Checklist

What Every Homeowner Should Know Before Replacing Their Boiler
By FlowHeat.ie | Serving Monaghan & Dublin

🔍 1. Check the Age of Your Current Boiler

• Is your boiler more than 12–15 years old?

• Have you had multiple breakdowns or expensive repairs?

• Are your energy bills creeping up?

➡️ If yes, you may save money long-term by replacing it with a modern A-rated boiler.

💡 2. Know Your Boiler Type

There are a few main types of boilers in Irish homes:

• Combi Boiler – Compact, heats water on demand. Great for smaller homes.

• System Boiler – Uses a hot water cylinder. Best for homes with multiple bathrooms.

• Regular (Conventional) Boiler – Has a water tank and cylinder. Common in older homes.

➡️ Not sure what you have? Don’t worry—I will explain what works best for your home.

💶 3. Set a Budget (and Expect Clarity)

• A standard boiler replacement usually budgets between €2,000–€3,000.

• Get a clear, fixed-price quote—beware of vague “from €X” pricing.

• Ask what’s included (e.g. power flush, thermostat, removal of old boiler).

➡️ I give a full, no-nonsense quotes with everything explained in plain English.

🛠️ 4. Consider These Extras

Not essential, but worth asking about:

• New smart thermostat or heating controls

• Power flush to clean your system before installing the new boiler

• Zoning for better control of upstairs/downstairs heating

• Advice on future-proofing with energy-efficient upgrades

• Get a carbon Monoxide alarm!

📜 5. Check the Warranty

• Most quality boilers come with 1–10 year manufacturer warranties

• Make sure you register the warranty correctly after installation if need be

• Annual servicing may be required to keep the warranty valid

➡️ I help with registration and give you all the documentation you need.

🟢 6. Ask About SEAI Grants

You may qualify for a grant through the Sustainable Energy Authority of Ireland (SEAI), especially if you’re also upgrading controls or insulation.

➡️ Shane will explain what you’re eligible for and help guide the application process if needed.

📞 7. Choose a Plumber You Trust

• Look for real customer reviews

• Make sure they’re fully insured & registered; RGII

• Avoid those who rush you or give vague answers

➡️ At flowheat.ie, you deal with one person, start to finish—no sales teams or hidden costs, just me!

Many homeowners don’t know what to check before hiring someone for a gas boiler installation in Ireland, and it can make a huge difference in terms of safety, cost, and reliability. Here’s a clear checklist you could even use on your website to educate customers and build trust:

What to Look for in a Plumber or Company for Gas Boiler Installations in Ireland

When replacing or installing a gas boiler, the installer you choose is just as important as the boiler itself. Here’s what you should look for:

✅ 1. RGII Registration (Legal Requirement)

• Only a Registered Gas Installer (RGII) is legally permitted to install, repair, or service a gas boiler in Ireland.
  
  

• Always ask for their RGII number and verify it on the official register.
  
  

✅ 2. Clear, Written Quotes (No Hidden Costs)

• A trustworthy company will provide a detailed written breakdown of costs, including:
  
  

  • Boiler price
    
    

  • Installation labour
    
    

  • System flushing
    
    

  • Flue, controls, or pipe upgrades
    
    

  • Removal of the old boiler
    
    

• Be cautious of vague “all-in” quotes that leave room for add-ons later.
  
  

✅ 3. Experience & Reputation

• Look for installers with years of experience in gas boiler installations.
  
  

• Check for reviews, testimonials, or recommendations from other customers.
  
  

✅ 4. Warranty & Aftercare

• A reliable installer should:
  
  

  • Register your boiler with the manufacturer for warranty.
    
    

  • Provide at least a 5–10 year warranty (depending on boiler brand).
    
    

  • Offer follow-up servicing or support if needed.
    
    

✅ 5. Transparent Advice (Not Just Sales)

• A good plumber will assess your heating system and recommend the best boiler size and type for your home, not just push the brand they make the most margin on.
  
  

• Be wary if they only ever recommend one brand without explanation.
  
  

✅ 6. System Flushing Included

• Reputable companies will always carry out a power flush or chemical flush before fitting a new boiler.
  
  

• Skipping this step is a common shortcut that can shorten your new boiler’s lifespan and void the warranty.
  
  

✅ 7. Insurance & Certification

• Always confirm they have public liability insurance.
  
  

• Ask if they provide RGII completion certificates after installation (this proves the job was done legally and safely).
  
  

✅ 8. Availability & Support

• Do they offer after-hours support or emergency callouts if something goes wrong?
  
  

• Do they provide ongoing servicing packages to keep your boiler in top condition?
  
  

✅ 9. Energy Efficiency Knowledge

• A quality installer will also help you save money long-term by advising on:
  
  

  • Heating controls
    
    

  • Thermostats
    
    

  • Smart home integration
    
    

• This can reduce heating bills and may qualify you for SEAI grants.
  
  

✅ 10. Professionalism & Trust

• Do they arrive on time, answer questions clearly, and respect your home?
  
  

• The best installers are transparent, friendly, and put safety before profits.
