01What is being requested

Market exploration into intermediate solutions for the replacement of central heating boilers in the de Polders district, focused on no-regret measures that are compatible with a future source network. The focus lies on mapping technical specifications, contract forms (rental, lease, buy-back) and possibilities for repurposing or circularity of installations.

With this market exploration, the Municipality of Houten wishes to investigate which possible intermediate solutions can be offered to residents who must replace a heating appliance before a heat network has been established, so that they can still switch over to the heat network favourably once the heat network is realised.

02Strategic insight

“
Strategic insight · AI analysis
Focus on no-regret solutions that are both profitable and technically compatible in the event of a potential source network as well as in a scenario without a source network (e.g., via all-electric options). Ensure a transparent offering of flexible contract forms such as rental, lease, or buy-back, including full visibility into de-installation and re-installation costs. Explicitly substantiate the possibilities for circularity and repurposing, as the municipality views this as an opportunity for addressing energy poverty or scaling up to other districts.

10Frequently asked questions

What is the purpose of the market exploration?
The purpose is to investigate which intermediate solutions can be offered to residents who must replace their heating appliance before a heat network is available, so that they can switch over to the network favourably at a later date.
What is meant by a 'source network'?
A source network is a very-low-temperature heat network (vlt-net) that delivers low-temperature heat from sources such as surface water, WKO's (Aquifer Thermal Energy Storage) or other ground sources to homes and buildings.
What is a 'no-regret measure'?
A no-regret measure is a measure that does not hinder the future connection to the source network and does not cause unnecessary extra costs.
What is meant by an 'intermediate solution'?
An intermediate solution is a temporary heating solution that residents deploy to replace the central heating boiler until a potential source network is available.
