What affects scope

  • Existing boiler position, flue route and condensate route
  • Hot-water demand and radiator performance
  • Pipework, controls and any system-cleaning work
  • Access and the gas, oil or LPG option being considered

What to send first

  • Current boiler position, flue route and any accessible pipework details
  • Hot-water demand, radiator performance and the controls already in use
  • Whether gas, oil or LPG is being considered
  • Any access constraints around the boiler, flue or condensate route

Good fit when

  • An existing boiler is being replaced
  • A survey is needed to choose the right boiler and controls
  • The wider system may need pipework, radiator or control changes

If the existing boiler may be repairable, compare Boiler Repairs before choosing replacement. Boiler Servicing and Central Heating cover ongoing care and wider system work.

Boiler installation in East Sussex needs more than swapping one appliance for another. Optimum HVAC engineers check the existing boiler position, flue route, hot water demand, radiator performance, condensate route and control setup before recommending a gas, oil or LPG option. That protects the customer from being quoted the wrong boiler for the house.

Survey, sizing and boiler choice

The visit separates a like-for-like replacement from a job that needs pipework changes, system cleaning, a magnetic filter, weather compensation or upgraded controls. Optimum HVAC can talk through Worcester Bosch, Vaillant, Viessmann, Ideal and Grant options, then explain which warranty route applies to the chosen model.

Installation and handover

The work is planned around safe access, neat pipe routes, flue compliance, protection for floors and a clean handover. If the existing system has sludge or cold radiators, the quote should link boiler replacement with boiler servicing, boiler repairs or central heating upgrades so the new appliance is not carrying an old system problem.

What our customers say

“Zak is knowledgeable, detail oriented and does not just a functional but an aesthetically pleasing AC installation. Very happy with the Zak and the work. Zak always kept us informed and updated about everything going on which was very nice. I highly recommended him.”

Satish

“Installed multiple air conditioning units. Zak worked hard in both the design and installation phases to ensure that disruption was at a minimum, and the end result was as unobtrusive as possible. The latter mattered a lot to us, as with a larger install it would be easy for there to be cables all over the place. Zak himself was personable and knowledgeable, and I'm very happy with the end result.”

Jim McDonald

“Thoroughly recommend Zac from Optimum. Knowledgeable, helpful and his work shows his experience. Efficient and cleaned up afterwards, takes pride in his work. Gave solid, honest advice (not just the easy route, the quick fix). See photos of my old hot water cylinder and new.”

How do I get a price for boiler installation?
A safe quote depends on boiler type, current boiler position, flue route, pipework, controls and hot-water demand. Send the details or photos first, then Optimum HVAC can confirm the right scope without guessing.
Will boiler installation disrupt the property?
The amount of disruption depends on old-boiler removal, flue work, pipework changes and how heating or hot water is kept off for the shortest practical time. The scope also needs to account for boiler type, current boiler position, flue route, pipework, controls and hot-water demand, so Optimum HVAC should confirm the work route after seeing the job rather than making a blanket promise.
