When a heater needs replacing rather than repairing

A tank has a service life. Past about ten to twelve years, most of what goes wrong is not worth repairing, and a tank that has started to rust from the inside cannot be fixed at all.

These usually mean replacement rather than repair:

  • Rusty or brown hot water, when the cold runs clear
  • Water pooling around the base of the tank
  • A rumbling or banging noise when the burner fires
  • Hot water running out much sooner than it used to
  • The tank is past twelve years old and something has failed

What a replacement involves

We drain and remove the old tank, set the new one and reconnect the water, gas and flue. We fit an expansion tank where the system needs one and take the old heater away.

Tank or tankless

A tank stores hot water and is often simpler to fit into an existing setup. Tankless water heater installation needs a separate check of hot-water demand, fuel supply and venting. We compare the options that fit your home before you choose.

Gas, venting and the expansion tank

Most heaters we replace in Castle Rock and Parker are gas. We make sure the flue suits the new unit and include an expansion tank where a closed water system requires one. If the gas line or shut-off needs changing, we explain the work and price before starting.

How we price it

We assess the tank, venting, gas line and available space, then explain the suitable options and prices. You approve the work before the existing heater is drained.

What is included

  • The old unit drained and removed
  • New tank or tankless unit set and connected
  • Water, gas and flue connections re-made
  • An expansion tank where the system needs one
  • The old heater taken away
  • The area cleaned up before we leave

How it goes

What happens when you call

  1. Tell us what it is doing

    Tell us if you have rusty water, a puddle under the tank or no hot water, and when it started.

  2. We look, then price it

    Tank, venting, gas line and space. You get the options that fit, with a price on each.

  3. Swap it and take the old one

    We drain and remove the old tank, set the new unit and reconnect the water, gas and flue. We take the old tank away.

Common questions

Before you call

How long does a water heater replacement take?

A straight swap is usually a half-day job. Re-routing gas or venting adds time.

Do you take the old tank away?

Yes.

Can you fit a tankless unit instead?

Often, but not always. It depends on your gas supply and venting. We will look before recommending it.
