Richmond sits entirely on low-lying delta islands, which means almost no basements and a very specific approach to placing a boiler and manifold.

Quick answer
Hydronic and radiant floor heating circulates hot water from a gas boiler through in-floor tubing or radiators. Richmond is built entirely on flat Fraser River delta islands with a high water table and soft alluvial soil, which is why most homes here are built on crawlspaces or slab-on-grade rather than full basements, and why boiler and manifold placement always has to work within that constraint rather than assuming a below-grade mechanical room is available.

Richmond's entire land base sits on soft, water-saturated delta soil protected by a ring of dykes, and that soil condition makes a conventional excavated basement impractical for most residential construction. The overwhelming majority of Richmond homes are built on a crawlspace or a slab-on-grade foundation instead, which means the boiler, manifold, and any condensate drainage need a design approach suited to those foundation types from the start rather than retrofitted around a basement that simply is not there.
A high water table across much of Richmond means condensate drainage routing deserves particular attention, since a crawlspace that already sits close to the water table is not an ideal place for a condensate line to simply terminate. A proper drain connection to the home's plumbing, rather than an informal discharge point, is the standard approach here.
Gas and mechanical permits for hydronic work go through the City of Richmond's building department. The gas connection must be completed by a Technical Safety BC licensed gas fitter — CANRO holds gas licence LGA0043870 and boiler licence LBP0046450.
As a ballpark, not a quote, boiler installation supporting a hydronic system typically runs $6,500–$14,000+, with slab-on-grade new construction sometimes on the lower end of complexity and older crawlspace retrofits varying more depending on access. An in-home assessment gives an accurate number for your specific foundation type.
A straightforward boiler replacement in an older Richmond crawlspace home usually means working within the existing access point and distribution rather than redesigning the whole system, since the original installer already solved the foundation-type challenge once. New construction or a major renovation gives more flexibility to plan the slab layout and tubing routing from the ground up, which is when in-floor radiant heating tends to be most cost-effective to install, since there is no need to retrofit around existing framing or flooring.
Safety note
Hydronic and radiant systems are heated by a gas boiler, so the same rules apply as any gas appliance: leave the home and call FortisBC at 1-800-663-9911 if you ever notice a gas odour, soot, or a headache that eases outdoors. Gas fitting, venting, and boiler work must be done by a Technical Safety BC licensed gas fitter.
Richmond sits on soft, water-saturated delta soil with a high water table, which makes a conventional excavated basement impractical for most homes; crawlspace and slab-on-grade construction are standard here instead.
Yes, in-floor tubing is commonly embedded directly in a slab foundation, or run beneath the main floor in a crawlspace, both of which are standard approaches in Richmond.
It is routed to a proper connection in the home's plumbing rather than an informal discharge point, which matters more here given the high water table under many lots.
Yes, through the City of Richmond's building department, and the gas connection must be completed by a licensed gas fitter.
It can involve more careful planning for access and tubing routing, but it is a routine and well-established approach given how common crawlspace construction is throughout the city. Working with an installer who is familiar with Richmond's typical crawlspace and slab construction makes a real difference in how smoothly the project goes.
As a ballpark, not a quote, expect $6,500–$14,000+, with the exact figure depending on foundation type and access; an in-home assessment gives an accurate number.
