Plan the boiler and the work around it together.

RJ Sam’s works on the boilers already in your home, across brands. We assess the equipment and explain compatible repair, care or replacement options.

Start with your home

What should the replacement improve?

Compare the existing fault and equipment condition with the parts of the system a replacement would retain or change. Revisit room needs rather than assume the old size and layout remain right.

Explore equipment options

Replacement is one option to compare with the diagnosed repair and the remaining equipment condition.

Compare the repair option
Existing radiators and piping
Assess their condition and how well they serve each room before deciding what stays.
Heat demand and water temperature
Room needs, operating water temperature, pumps and zones affect the boiler that fits.
Household hot water
Mention an indirect tank or combination arrangement so hot-water needs are considered with space heating.

Before you agree

What should the proposal include?

Compare the full installed work, what stays, what changes and what is excluded. Review the proposed price and actual equipment and labor terms before approving the project.

Written-scope guide

Free written HVAC installation/replacement estimate

Review a written proposal based on the home’s heating/cooling needs, existing equipment and supporting installation work.

Compare the sizing basis, retained components, price, exclusions and startup/handover. Confirm removal, permit and coverage responsibilities for the actual project.

Boiler selection
Explain the equipment and heating requirements used in the selection.
Piping, pumps and zones
We’ll identify components to retain or change and the proposed control arrangement.
Venting and drainage
We’ll specify the work needed for the proposed equipment and applicable permits.
Connected hot water
Include relevant household hot-water connections, startup and handover.

What affects the installation price?

Heat demand, radiator operating temperatures, pumps, zoning, venting and accessible piping affect replacement. Identify which distribution components can stay and which need changing.

Know what to expect

From planning to using your new system

  1. Confirm the plan

    Review the selected equipment, included work, price, timing and access before arranging the project.

  2. Prepare for the work

    Discuss equipment locations, removal routes and what you need to prepare. The work follows the agreed scope.

  3. Check operation and explain care

    Check the installed heating system and controls; explain operation and care for the selected equipment.

Before you decide

Planning questions

Review the common questions and use the project scope planner to prepare questions about the equipment and work involved. Your home will need an assessment before a quote is prepared.

What should be checked beyond the replacement boiler?

Heat distribution, water temperatures, pumps, zones, expansion arrangements and any indirect domestic-hot-water connection affect fit. Ask whether system cleaning, control changes, venting, removal and startup are included. Confirm the actual fuel and system types supported before arranging the assessment.

Do I have to replace my radiators?

Not automatically. Radiators and piping that remain suitable may stay. Their condition and performance need assessment.

Is a higher efficiency rating enough to choose a boiler?

Review the heating water temperatures the home needs and the installation requirements alongside the rating. Operating conditions affect a condensing boiler’s efficiency.

What if I have a steam boiler?

Describe how your home is heated as best you can. A model name is helpful if you already know it, but you do not need it to ask for help. We’ll identify the system and confirm the service we can provide.

How long will the work take?

Timing depends on the agreed scope, equipment, access and supporting work. Confirm the schedule, expected heating, cooling or hot-water interruption and preparation for your project before work is arranged.
